• converse with others on the phone using the loudspeaker in public (haven't you heard of the earpiece?!
• stare at you for no rhyme or reason (don't call it a habit it is NOT a habit to stare it is just a very rude thing to do!!)
• say "chill". i'm sorry i just can't.stand.it. (it actually makes me angrier haw.)
• sneeze without covering their mouths/ saying "excuse/pardon me".
• think that it is only right for me to hold the door for them and not say thankyou (wtf?)
• bore my pants off (sorry)
• waste my time (no apolgies here)
• think extremely highly of themselves
• annoy me to no end.

this list would be pretty much endless.
