GnR, fair enough and I agree the trust aspect is the most important.
My wife never had issue with me going out late at night because;
1. it was not regular
2. she knew the ppl I was going out with
3. she was welcome if she wanted to
4. she knows me
That being said, switch the table for a second: would you be happy to let your girl go to a "men's bar", drunk, where she would be surrounded between seconds by half naked guys trying to seat on her lap?
I trust my wife and so does she but I know that I wouldn't like her to be in that situation, so I also avoid to be in that situation :-)
I agree on that, but, sometimes boys are boys and we can get a bit primitive, where we would like to have a laugh, its like watching a screwball comedy, more than anything.
But yeah, may be it'd be better I don't go there, even for a laugh.
