It’s definitely not an easy task to buy a present for a father. The older they get the less likely it is that something will really strike them and make them happy even for a few minutes, unless you can afford spending a fortune. Fathers are in a sense aged kids who have became difficult to get enthusiastic about new things as they have tried pretty much what they could afford. Buying them a Ferrari or a liar Jet would definitely work and make them look like 10 year old boys again but it seems unlikely that anyone would afford anything like that.
