Here's a hint to all you wrenches with tikes.
1. Don't buy them toy tools. It's a waste of money. They want to use the tools you're using. Just hand them all over.
2. Don't let them ride their tricycles with a wrench in hand. They will stop continually and want to "fix" their wheel.
3. Don't swear while fixing your bike. The little ones are like tape recorders.
