Sorry for the shortness. I actually wrote this months ago, but edited it a bit. I might add more one day.

Clary honestly didn't really think she'd have to teach Tessa about social media. Unlike Jem who had been a Silent Brother and didn't get internet, Tessa had had a lot of time to get used to everything twenty first century. Must be because she had better things to do than waste hours upon hours on Facebook, or watch Vines.
"So, what is this?" Tessa pointed hesitantly to the screen. Clary glanced away from the YouTube search bar to the corner where a pop up ad had come up.
"Uh..."
"Gracious, she's showing a lot of skin." Tessa's eyes widened in horror.
"That's just an ad for an online game." Clary hastily clicked search and the almost nude warrior girl vanished.
They watched an hours worth of videos, both complaining loudly at the five second ads, and the ads that didn't let you skip.
"We should make you a Facebook account!" Clary quickly typed it in the search bar.
"Oh! Jem told me about this."
"He didn't tell you what happened did he?" Clary asked worriedly.
"Okay, so now you need a profile picture." Clary held her camera up to and just as she was about to take the picture, Jem dived to the ground.
Instead of a picture of Jem, she had a picture of the lovely blue wall that had been behind him.
"Sorry," Jem got up sheepishly. "I'm a bit camera shy."
"No problem, we can try again." For good measure, Clary turned the flash off.
After numerous attempts, (he was looking a little bruised,) Clary eventually duck taped his arms and legs to the nice-shade-of-blue wall and the result was a shell shocked Jem taped to a wall.
"No, why?" Tessa raised an eyebrow.
"No reason, you aren't camera shy are you?"
