When i was younger I sent a message to a girl (Girl A) I was seeing, saying 'thanks for the nice dinner and awesome sex last night'. After I'd hit send I realised I'd meant it for the other girl (Girl B) I was seeing, so rapidly trying to backtrack I sent a message to Girl A saying I meant something last week. I then sent this accidentally to Girl B.
After tha I switched my phone off for a few hours, went to the pub with my flatmate and got drunk. When I turned my phone back surprisingly I found i'd been dumped. (I was only 16 or 17 at the time, so it was still in my formative years lol)
