Adorable children leave envelopes of money taped to S.F. parking meters

Some generous children made Valentine's Day truly special this weekend by taping envelopes of change to parking meters in Cow Hollow.

The youngsters (presumably, given the sweetly youthful handwriting and drawings), left change on parking meters and at bus stops with adorable messages like "take care!" and "to parents: to help you out!"

The envelopes were spotted by ABC7 News reporter Melanie Woodrow:

Thanks to some of San Francisco's littlest citizens for making our world a little brighter. We could all learn from their act of kindness.
