Question: What should I get my Dad for Father’s Day?
Answer: Maybe He should give you some backbone to make decisions! Whay are you asking me?
Beyond that though, don’t get him a tie unless you are six years old. Cash from an economics point of view has the highest marginal utility (gift cards essentially the same), and anything that saves time of headache (like mowing his lawn or getting someone else to do it) is appreciated.
Try to create an experience though, something that you will actually talk about because you remember it in the future. It doesn’t have to be sky diving or anything nuts like that, but something that he has wanted to do and would appreciate.
