I get asked about the cost of my "toys" a lot. I work with almost 100% women who are moms, and we don't make much money. Mostly they're perplexed by how I can afford toys at all. I explain that not having kids frees up an extraordinary amount of disposable income.

BTW - They tend to look incredulous when I reply that my roadbike was $1100, it's usually followed up with "but I got my son a fancy new mountain bike for xmas at Wal Mart for onlt $150!!!).
