Have you ever chatted with someone, thought it was going good, and then all of a sudden its like who are you. Personal attacks and assumptions

Holy crap, chatted with someone, and went well, good joking conversation and then one day not feeling like chatting and "BAM" this person changes and gets snitty and bitchy. Like WTF. I talk to whom i want to, if I'm not in the mood to talk to you then accept it and suck it up.
