I hate it when someone just comes up to you and sings a random song. I'm not gonna sing along to you. I don't know what to say when you do that. I hate it when a song comes on around my singing friends because they will be singing it around me when it's done. My friend likes to sing so she randomly comes up to me and sings a song. I have no idea how to reply so I'm just left there staring somewhere else. Please, stop doing this. It is VERY, VERY AWKWARD. I would never do this but my friends just come up to me and sing. Very awkward.
