My best gift:
A secret Santa gave me $1000, several gift cards, Christmas treats and toys when I was unemployed, broke, and had a 3 year old I was raising without child support or family to help. This came on Dec 1 that year and saved me. I was able to pay the rent with the money and get food with the gift cards. I got a wonderful job on Dec 12 that year, and life was very good. I never found out who the Secret Santa was.
My worst gift
This came when the employees that I managed got together and bought me some work clothes. This odd gift was made odder in that none of it suited me in color, style or fit and all looked horrible. I wore each of the outfits once to work and then never again. The horrified looks of the people who gave me these clothes was enough to let us all know we had a fail.
