Accidentaly, all the time. I do it too even though I try not do and always apologize when it happens
But this one time I was at my best friends' bday party and her little sister (who had a crush on me at the time) thought it would be really funny to spit on me. I got so freaking mad and I wanted to beat her up but she was a little girl and besides, she was my bf's sister so I couldn't possibly do that. Also her parents were home
