LauraNorder, don't beat yourself up, I lurked on this site for more than two years, only joining when I finally got an email address, I still don't use it though.
It didn't take me long to realise that posting a comment is far different from simply reading comments. It takes time to become known, to fit in with a group of people who "know" one another and to become accepted.
As for foot in mouth. I said to my wife that I had seen a lady who had managed to get the hem of her skirt caught up in by the elastic in her knickers, adding that I looked away and hoped someone else lets her know.
Smiling, my wife said, "you can talk," as she looked towards my crotch. I had been walking round all day with my flies undone.
