For me this demonstration of signature strength was phenomenal. The five students for whom past due library debts were being paid accepted the act with generosity even though I was not expecting anything else, but a thank you. This was done overtime without allowing each person to know what I was doing. The activity was conducted on five different occasions. My daughter told me that her teacher loves Starbucks drinks and this I thought was a great opportunity to show my appreciation through this kind gesture and supplementing it with a thank you card to avoid any suspicions.
