Okay. Firstly, this is an amazing thread. So much fail haha. I have a decent one, not 100% my fault, but certainly copped bucket-loads of shit about it off mates, and still do occasionally - some 2 years on. Having a sister two years younger than me has always provided me with any number of her friends to chat up with an easy starting point. Though she has this one friend, who is an absolute 10/10, and I barely ever even considered it to be the faintest possibility. Until one night at a nightclub, I told my sister how amazing her friend was. My sister (a solid wing-woman in her own right) went over and told her friend god know's what, but her friend came over on the dance floor, smiled and started kissing me straight up. We spoke for a while after this and hooked up several other times that same night. Exchanged numbers, but I didn't contact her at all for a couple of weeks. Cue the night of the fail... A fortnight later I went to the train station to head into the city, and she was doing the same, both on our own. She teased me about not contacting her and we flirted the whole way to the city on the train. She asked me to come to the club she was going to with her mates, but I had prior arrangements I was obliged to honour. She messaged me almost instantly after we got in separate taxis telling me she wanted to catch up later and had an hotel room with her guy mates, but would prefer to stay elsewhere. I went to my mate's event, got sh*t-faced, messaged her several times during the night and she was keen, my phone was going flat though so I turned it off to save power. I got too drunk, forgot to turn it back on until 4am, at which point I had numerous messages/missed calls from her asking when she could see me/stay with me. I apologized but got no reply, didn't see her for two weeks, in which time she started dating a mate of mine (broken up now, but were together for over a year) and is now off limits. I have never lived it down. Not sure why I said it wasn't all my fault, in hindsight - massive fail.
