I think very carefully if I get an invitation to a wedding or party, in ways I never used to.
It can incur a lot of costs for guests. Recently a distant cousin I've barely seen invited us to his third wedding. He lives far enough that it would mean a hotel bill for us. Other costs are new outfits, the present, petrol - it adds up to not being at all worth it. So I've made my excuses.
Another time a peripheral friend, who we only see occasionally, was giving a big party for her 50th at a posh hotel, again it would have cost quite a bit including taxis. So we dodged it. There are even people who ask you to events and you must buy your own drinks. Others get married abroad and expect friends to fly there at their own expense. Still others who do stag or hen parties involving everyone paying all sorts of costs including staying overnight.
Am I churlish or practical? We are retired and live on a budget and cost of living is going up and up. So we just don't go unless it's close family or a very close friend.
