I Spilled Milk All Over Class Today

Hey guys, so today at lunch I accidentally knocked over my milk carton and it went everywhere! It was all over the table, and even spilled onto my friend Lily's homework. Everyone started staring at me, and our teacher had to bring a mop because there was just so much liquid. I felt really embarrassed and stupid after that. But then I started wondering, is it really such a big deal? Has anyone else ever accidentally made a mess like this before? Am I the only one who feels super guilty about it?
