Hello ladies - blimey this thread moves fast. I reckon this sudden block stuff is completely non gender specific - not that you would of course, but please don't tar us all with the same brush!
Certainly in my limited experience us blokes get it all the time too. The pièce de résistance was before I'd posted any pictures up on one site. This girl sent me a really long email eulogising about how my profile (which was, admittedly, quite outstanding) was so different from the norm, and how I sounded fascinating....oooh and could she see some pictures please???
No problem, I'll dust off (read upload) some classic shots for the profile toot sweet.
Blocked.
Does wonders for the confidence that!
Another one is related to the classic 'Why hasn't he/she replied yet'
We get it too. There was one who seemed to be able to know the exact amount of time to wait before replying so that just as you were giving up hope of ever hearing from them again (i'm talking weeks), in popped a message. It was infuriating. And then, another was quite the opposite. She wanted a message seemingly every minute. She got terribly angry when I didn't reply immediately, and then blocked me when I had the temerity to not reply for a day due to me being struck down with the old manflu. That's the problem with online stuff (and I guess our lives these days) - everyone panics because we all assume everyone is constantly accessible.
This is why I much, much prefer real life!
