I am a big believer in helping where I can. I paid for a woman's fuel a few months back because she had forgot her wallet, was struggling with a little baby and was close to tears when she realized she couldn't pay. It was $20 and it saved her heartache. DH thinks it's mad sometimes but I remember when mine were little and things were hard, just little things made my day better. I didn't expect her to pay me back (even though she offered repeatedly), I was just trying to do a good thing for someone. We try and pass that onto our kids, being nice to others and helping people when they need it (and so far most of it is sticking). I can't say to them do xyz and not practice it in my own life ITMS.
