|The Random Acts of Kindness Barnstar|
|Dear Gandalf61, thank you for the kindness that you've shown towards me. I do not believe that we've ever interacted on Wikipedia before but nevertheless, you stood up for me. I really appreciate this act of charity and hope that God will bless you and your family in abundance. The image in this barnstar has a smile in it, which you brought to my face today. I hope that this barnstar will do the same to you. Your new friend, AnupamTalk 03:41, 2 May 2012 (UTC)|
