that SUCKS!
I know what you mean about annoying habits though...
When I was living with my mom last year ugh..it was awful. I've never in my life known anyone who can eat cereal so loudly. I swear - she must purposely slam her spoon against the bowl - because throughout the cereal eating you hear the clanking CONSTANTLY and it's LOUD!!
Don't even get me started on her with grocery bags......they're loud to begin with but ugh...
