What REALLY grinds your gears?

i've had a lot of miscommunications in my youth, but i have no one to blame but myself.

one of my favorites was in a crowded pet store in the mall around xmas time. a man near the middle of the store (right next to me, in my ear) was calling loudly to his son in the rear of the store. making no effort to actually move towards his son, calling his name "joshua!" several times, i just turned towards him and said "my name is kyle". he was furious and said through his teeth "i was talking to my son!".

i didn't feel like making any more trouble but i wanted to ask why he was doing it in my ear instead slithering his lazy ass to his son, who obviously didn't hear him, or was ignoring him.
