Girls do this constantly and it bugs the heck out of me

Why is it that whenever I end a conversation with a girl on any internet messaging service they can’t just end the conversation. Why must they say, bye 4 or 5 times. Its usually like this:

Me: well it was great talking to you- take care

Random girl: bye

Me: close the dialog box and go on with my business

Random Girl: 2 minutes later- something pops up and says “you too”

Random Girl: another 2 minutes go by and she says “take care” then it was great talking, then cya, then peace and then ttyl, then sometimes a good shabbos or have a great day etc…

Dude I said good bye because I didn’t want to chat any longer- why do girls have to do this.

Guys simply say “peace”
