we have two bikes. one works to pull the kids in the pull-behind thingie. that's the one i usually ride. r is planning on taking both bikes. i asked him to help me buy a new bike so i can still tow the kids this summer. "why should i help you buy a bike?" what do i say? and by "what do i say" i guess i meant, what do i say to such a ridiculous question? what is there to say?
