Me and my husband are too old?

My husband is 35 and I'm 38. We have 3 kids together. We went out with his brother who is gay to a gay club. It was our first and ONLY time out in 5 months. We both work from home so we are always around our kids. Our kids are with my FIL for the weekend. So we got absolutely hammered. Me and my husband both love gay clubs because there's a type of freedom in gay clubs that just aren't in straight clubs. We were dancing and all over each other but so were so many other people. They started playing apple bottom jeans and that's when we really started dancing sexually (like many others). My husband has a way bigger ass than me so when the song said gave that big booty a slap I gave his a slap lol. And the club has a strippers pole for people and my husband used to be a pole dancer so he was on the pole and I put a dollar or something in his pants and then I got on the pole with him and people were cheering us on. We had a fun time. So today this morning I had gotten a message from some women that goes to my son's school. I've only spoken to her a few times because she tried to get me to joined the PTA. She said she was at the club with her friends to have a drink and she almost came up to me when she saw me but didn't because she was repulsed by our behavior and said there's nothing wrong with going out to the club but me and my husband were too old to be acting like that and we are parents and to leave the pole dancing to the 20 year old gay dudes there and she's disappointed because she thought me and my husband were more mature than that. I had a reread the message and think "Is she serious? She really went and sent this to me". She was repulsed by our behavior because we were older and have kids even though this isn't a place FOR kids so why should we tone it down when no kids will be there. So just because we're old?
