"So I was thinking, if I alter some of the coding for my suit, maybe I could be able to check Facebook and Tumblr while I'm still airborne, y'know?" Tony Stark rambled on to Dr. Banner. "Picture this: I'm cruising along when suddenly, out of the blue, I see Grey Gargoyle doing his thing. I'm gonna wanna take a quick picture and upload it to Facebook with a nice, sarcastic comment, right? So we'd have to go into the general settings and edit the- Bruce? Bruce! Are you even listening to me right now?"
Bruce Banner was sitting across from Tony, head in his hands, a rumbling snore piercing the silence.
"Bruce?" Tony inquired, curious to whether Dr. Banner had actually fallen asleep during Tony's new, original, innovative, ground-breaking idea. Realising that this had happened, Tony snapped louder, "Bruce! Wake the HELL up!"
Dr. Banner jumped, clearly caught off guard. "Wha-"
"I was talking to you and you fell asleep!"
Bruce rubbed his eyes sleepily. "Sorry, I'm a bit-" he was interrupted by a wide, lethargic yawn, "tired today."
"Too sweepy for my stupid wittle idea?" Tony teased in a baby voice.
"No, just... I haven't been sleeping well or at all these past few days. So much stress..." he muttered, holding his head in his hands. Tony felt guilty at once for mocking him.
"Why don't you go to bed and rest and I'll tell you about it tomorrow?"
"No, it's..." Bruce yawned again, "okay."
"C'mon... off to bed then!" Tony said, leading the brilliant man to his bedroom.
