#classes taken

I kinda find it bothersome and a bit annoying when people ask you what classes you're taking when you're in upper division...because once you tell them the most common look is a confused look.  -_- Like, it's an upper division class made specifically for my major, of course you wouldn't know what it is but you ask anyways.  There isn't a point to knowing what classes I'm taking when we aren't taking it together and when they don't want me to explain what it is lol.  So it's a pointless question...:/ cus all I get are weird looks.
