Don't piss me off

First thing in the morning and I don't even know you! Couple of days ago I get an offline message on my messenger from some person. I've been busy so I didn't get a chance to respond. I sign in just now and person writes "I get the feeling that you are a hoax." Ok....asshole!
Number 1: I don't know you.
Number 2: Some of us have a life and aren't on messenger 24/7.
Number 3: I really don't give a fuck what you think of me.

Glad to get this off my chest.
