Being in a couple means you usually end up with lots of quirks.
But sometimes you don't even realise they're weird, and think the odd stuff you do with your S.O. is done by everyone. So we want you to tell us what weird couple quirks you thought were totally normal.
Maybe you guys use the same bath water and thought everyone else did too?
Or maybe you've even taken sharing to a whole new level, and exchange chewing gum on a regular basis.
Tell us what weird couple habits you assumed were normal in the dropbox below, and you could be featured in a future BuzzFeed Community post or video!
