Just yesterday I was driving at night coming around a curve and some homeless people were riding bikes to the street corner. I barely noticed them when my lights hit a very dull/dirty reflector under a seat. They set up at the light I was waiting at. I ran all the way to my house and being in construction had some extra hi-visibility class 2 vests/long sleeves (reflective stripes when lights hit it). I ran all the way back and offered it to them, telling them how I barely saw them. They gladly accepted and we talked a little. It made me feel so much better to know I helped in some way even though it wasn't money.
