Bumblebee

One word. Movies.

You both love them but when it comes to movie nights, someone else has to decide because it's always torn between your favorite movie and his.

Opti

Work.

He never stops so you just sit there glaring at the work.

"Why are you glaring at my work?"

"because it's taken you away from me."

"what? No, it hasn't."

Fight ensues.

Sam

Bumblebee.

It's always different. Either it's about one of you spending a lot of time with Bee. Or just fighting about who better friends with the cinnamon bun more.

Ratchet

Anything dealing with humans.

You're not fighting but it sounds like it when you're both ranting about something that happened on the news. Like someone being a complete and utter idiot. (whatever you find idiotic is what you and Ratchet rant about. But please don't start politics in the comments)

Jazz

Music

He likes newer music and you like older music. It's like you're in court and you're both lawyers representing the version of music you like best.

It goes on for hours and days.

Megatron

Plans for world domination and the end of Optimus.

Oh, this just goes back and forth till one of you decides that you're tired and just want the other to give you cuddles.

Barricade

Your job.

He wants you to stop. But you know you're already too deep in the job to stop.

"Well what if we set up a fake car accident, we make it look like you died. When in reality you're safe and alive."

"No, coppers. The moment they would find out I'm alive, I'm going to have assassins after me."

"I don't like the risk of your job."

"And I don't like the risk of yours but somehow, its ok for you to work under a War Lord but I can't be a getaway driver."
