*When people call you while they have another conversation with someone else while you just sit on the phone and listen
I was gonna say that!!! That irritates the HELL outta me!! You call me to talk to me, then TALK TO ME!!!!

People who come through my line at Bed, Bath & Beyond while on cellphones!!! Tell them you'll call them back!!!

Litterbugs!! I absolutely HATE people who throw their trash out their car windows. Why do ya think MY car is so filled with junk??? Put a damn bag in your car and throw your trash in THAT!!

Stupid STUPID people who don't spay/neuter their pets then wonder WHY they're pregnant!!

People who REFUSE to spay/neuter their pets because "they'll NEVER escape" so why bother???

I think that's a start. I could go on and on, but I'm sure someone else will come along and cover what I missed!!
