I agree with these comments. When I look at what I want to do in retirement, it's sip coffee, write, read, travel, enjoy art and good company. It is NOT expensive food, buy a fancy car, acquire and maintain multiple vacation homes, etc.
That said, I do acknowledge that there is a tension among friends. We have high incomes, and we have friends with much higher incomes (multi millionaires and a billionaire). For them, $700 dinners, $100 bottles of wine, extravagant trips are the norm. At the other end of the spectrum, I have long term friends who can't afford to go out to mid level restaurants. I have more fun going for long walks in the park, shopping at the local outdoor market, and sipping tea or coffee for an hour for $3 than I do eating a tiny piece of $30 fish and drinking too many glasses of fancy wine in a restaurant. Still, I don't want to lose those friends either.
While still working, I'm trying to live like a retiree, and I've noticed that retirees do fun cheap things like volunteer at the local museum, have movie night with DVDs from the library, and enjoy the happy hour specials at Bone Fish Grill one day a week.
