'This is the second day in a row that you've been to school on time,' Calvin said to his twin, amazed. The twins were sitting on Marty's bed talking, while they were listening to Huey Lewis and The News.

'Well, yeah,' Marty said, shuddering, 'I've been conscientious of being on time for school, since Ms. Coleman put me through all that torment the other day.'

'Oh, yeah, I understand,' Calvin agreed. 'I would hate to have gone through through that torment myself. We just happen to be very ticklish guys, I guess.'

'Yeah, but why do the soles of my feet have to be so damn ticklish?' Marty asked, grimacing. 'That is the absolute worst place on my body to be tickled.'

'I hear ya, Marty,' Calvin said, nodding with understanding. 'Since we are identical twins, we are going to be equally ticklish. Well, at least Ms. Coleman finally got you to take school more seriously. Really, Marty, education is important.'

'Yeah, I guess you're right,' Marty said, sighing. 'It's just that school is too boring.'

'That right there is the very problem you have, Marty,' Calvin said, gently. 'I find school to be interesting. You just have to have the right kind of attitude.'

Marty just sighed. He and Calvin may be identical twins, but there were definite differences between them. Like, for instance, Calvin loved to study and write reports for school - while Marty preferred to do as little work as he needed to pass. Marty figured that a lot of what they learned in school was useless info that he wouldn't ever need in real life. At times, Marty thought that his twin could be a little bit of a 'goody two-shoes'. Still, Calvin has come through for Marty many times - and, for that, Marty was grateful.

There was no denying that Calvin was Marty's very best friend in the world - even more so than Doc, Jennifer, and his buddies from The Pinheads. Within the last three months, since the twins have returned from 2015 and 1955, Marty had to spend some time sorting his memories out. Marty had a set of memories where his mother was an alcoholic, his father was bullied by Biff, and he didn't have a twin. It was hard for Marty to cope with retaining his memories of life without Calvin, which were side-by-side with his memories of growing up with Calvin. Calvin also had a tough time coping with the fact that Marty suddenly remembered a life without him. Still, Marty and Calvin had remained close friends.

'Are you okay, Marty?' Calvin asked, concerned. 'You're awfully quiet.'

'Sorry,' mumbled Marty. 'I guess I was just deep in thought. I'm still not sure if I ever want to go on another time travel trip. That week that I spent in 1955 really wore me out. It's was tough trying to get Dad to ask Mom out, so that I wouldn't be erased from existence. Then, on top of it, I was worried about Doc being shot by the Libyans. He was so stubborn, he wouldn't let me warn him about his future.'

'He was somewhat inexperienced back then,' Calvin said, gently. 'Anyway, he did eventually decide to tape the letter back together.'

'Yeah, that's true,' Marty said, sighing. 'Still, I was so depressed, thinking that I would return to a world where Doc was dead. He really has helped us a lot.'

'Yeah, I see what you mean,' said Calvin. 'I guess, in a way, I did luck out - by not spending the week in 1955, like you did. I remember feeling so jealous that Doc didn't invite me along to see the time machine, but not I understand why he didn't. It would have created a time paradox. I really would like to go on some more time travel trips, though. I can think of a lot of eras that I would love to see.'

'Well, yeah, I would like to see the '60s,' said Marty, nodding.

'Oh, Marty,' said Calvin, shaking his head, 'you really should be more adventurous than that. I guess you are pretty obsessed with rock and roll, aren't you?'

'No, I'm not obsessed,' protested Marty. 'It's just that, I cannot imagine life without rock and roll. I mean, listen, rock and roll is a big part of my life.'

'Then you are obsessed,' insisted Calvin. 'Admit it, Marty, you are obsessed.'

'No, I'm not,' protested Marty. 'Please stop saying that.'

'You are obsessed,' repeated Calvin, leaning over to tickle Marty's sides. Marty tried to tickle Calvin back, but his twin overpowered him.

'Please! Stop! Stop!' protested Marty, laughing.

'I'll stop, when you admit that you're obsessed,' Calvin said, with a teasing smile.

'I'm... not... obsessed,' Marty gasped, through laughter.

'Then I guess I'll just tickle you some more,' Calvin teased, as he tickled Marty all over. 'I'll stop when you admit that you're obsessed.'

'But... I'm... not... obsessed,' Marty protested, gasping from laughter.

After tickling Marty for five minutes, Calvin finally stopped. 'Gee, Marty, you really are stubborn, aren't you?'

'Nope,' protested Marty, as he began to tickle Calvin in revenge. 'Oh, listen to you laugh,' teased Marty, as he attacked Calvin's ribs. After about five minutes, Marty finally stopped.

'Okay, okay, I guess I deserved it,' Calvin sighed, as he laid back on Marty's bed.

'Oops, let's turn the tape over,' said Marty, as he waled over to the stereo.

'Yeap, you're obsessed with rock and roll,' Calvin smirked.

'Am not,' protested Marty, as he flipped the tape over.

'Are too,' insisted Calvin, with a smirk.

'Am not,' argued Marty, as he grabbed pillow from his bed.

'Whew, pillow fight,' smirked Calvin, as he grabbed another pillow.

Marty, however, used his pillow to pin Calvin onto the bed. Calvin then used his pillow to his Marty in the face, causing Marty to fall to the ground.

'Now I got you, Marty,' triumphed Calvin, as he used his pillow to pin Marty to the floor.

'Boys,' Lorraine called, through the door, 'it's time for supper.'

'Coming, Mom,' called out Marty.

'Marty, you are obsessed,' Calvin whispered, smirking.

Marty just rolled his eyes and remained quiet.
