I'm 52 and still enjoy going to these events, my mum, when she was alive, was the same and the wife lets me do what I want - as long as the bills get paid. Most of us put money away for these events to cover our costs so as long as its your money they shouldn't complain - would they much rather you be a drug addict, alcoholic or addicted gambler or would they much rather you go to these events (you could always tell them its an investment) where you meet people with similar interests . At the end of the day its harmless (but, at times, can be expensive) and where else would you meet big names from films, tv, sport etc. Enjoy yourself!
