My husband and I have always tried to Pay It Forward after we moved to this subdivision 37 years ago. I used to mow and weedeat the lawn of one of our neighbors who had MS. The giver does receive something in return when they pay it forward. They receive a blessing bigger than the gift or deed they give.
We are older now and I can't get out and mow like I used to, but we have an elderly neighbor lady who is homebound that we take her mail and newspaper in to her every day. We take her outgoing mail to the post office for her. She is a real blessing and encourager to us too.
Just a smile sometimes is a uplift to others, I know it is to me.
