No, this is all quite wrong. Provided you invest wisely, the assets you have acquired should be worth roughly what you paid for them. So you have spent nothing.
As opposed to taking your wife out for a meal, in which case all you will have as a result is a pile of cr*p.
The solemn moral of the tale is that you can have a bike hobby without it costing you very much, whereas having a wife is ridiculously expensive.
And does your bike expect you to spend your entire life doing things you don't want to do? Does it moan at you whenever you propose to do something you might enjoy? If wives were more like bikes, the world would be a much better place.
