People who repeat the same thing over and over and over and over! I think I got it the first 5 times you told me, buy a tape recorder to avoid vocal strain! Yesh!
Relatives who choose to go into long winded stories about relatives I don't know and couldn't give a flying fig about.
I have an I-Pod touch and can't tell you how many people just come and take it outta my hands so they can look at it. I don't mind that they wanna look but ask first!
