Mom:
*hands her the money*. " Here, this is to cover their coffee. Someone did something nice for me today, I want to repay the favor to someone else. "
Lady:
" Thank you, * smiles* I'll make sure to pass it along. Have a great day! "
Me:
" That was really nice of you, Mom. "
Mom:
" I looked in the mirror and saw that they were counting change, everyone could use a little help every now and then. "
