I have a twin brother and there are a lot of stuff that are really annoying about him///
-his friends expect you to have the same sense of humour as him or that you know all his secrets
-when people find out they always ask if you have twin telepathy
-parents ALWAYS compare you to them with grades or sports and clearly favourite the better one
-because they're in the same year as you, they always tell your parents what you got in a test or if you got a detention or not
