Thank you, dandylion!
"Notice what people do for you and thank them. The simple expression of gratitude is one of the ways that we give back to the giver. It feels good for our giving to be received and it makes us want to give again!"
My physical therapist relates it as completing an energetic circle. This especially includes accepting the gifts of positive words and compliments.
Allowing others to help us can also be a type of gift exchange.
"When you can ask and accept someone’s help, you are honouring who they are and what they have to offer."
