I totally know that feeling, Limewave! And I don't have kids, so I can't imagine the depth of it--only my little bit. I bought a duvet cover last week that I've been wanting for a year. I year! I did save up for it, and I still feel guilty for buying it.

I'm so glad that I'm happy with the bikes that I have and am not needing to buy any others. I have to get a new cassette and chain for one of them in July, I'm already dreading spending that money on myself.
