I shake my head at people who do this; yet recognize the fun, the experience, and camaraderie they get out of it.
We may label it silly or a waste of time, but as one poster pointed out above, we all have hobbies, pastimes that others cannot believe people spend time at or money on.
1. Hitting a yellow ball back and forth across a net.
2. Outdoor camping when the ground is hard, the air bag uncomfortable, the rain or mosquitos or cold inevitable, etc.
3. Going to a rock concert where you can only see the performer on a Jumbotron! And the music is so loud, your ears ring for days if not weeks afterwards.
4. Expensive diamond rings.
5. Large-scale ephemeral weddings that are so cliche, they all look the same and nearly bankrupt the bride's family! Time and money could have been better spent on a house downpayment.
6. People going to midnight showings of movies and spending $20-30 on an event they could enjoy more comfortably at home in their pajamas...
7. People going to drive-ins (the few that are left) and listening to a movie through a tinny speaker hung on the window!
8. People going to loud, smoky bars where there is often a line to get drinks!
You get the drift?! One man's treasure is another man's poison.
The ancient Romans had it right:
"De gustibus non est disputandum"!
