15. Double vision.
I’m an identical twin. My brother was visiting me at school and I invited a girl I met on tinder over. He doesn’t use Tinder, but obviously didn’t want to be alone for the night so I used the app to get him a girl too.
She thought he was me the entire time all the way up until she left the next morning. Right before she left she asked my brother a question about my rugby team that he just couldn’t answer. I got some angry messages afterwards.
