Contrary to the title, this is not a sex thread. Although I’m sure someone will drag it that direction soon. 
Actually, I have a pet peeve to share. Idiots who get on elevators (lifts for those across the pond) before letting people off. I know its not the law (should be!) but I am sure it is accepted etiquette. I don’t know how many times I have almost hit someone because they jumped in the car before I could get off. “Hey fast pants, wanna give me a chance to get OUT of here?!” Am I way out of line to expect a little courtesy here?
BTW, feel free to express your pet peeves. I have another one about sex, but I’ll wait until the thread heads down (pun inteded :D) that road before sharing.
