Pushing the friendship
There’s this guy at school that I’m really good friends with and he has another guy that looks just like him in the grade below us. One day, I was walking down some stairs and I thought that my friend was in front of me, so I gave him a friendly push. It turns out that it wasn’t my friend, it was his lookalike! To make things worse, I said that someone behind me had pushed me into him, but when I looked behind me there was no-one there!
