Hi George,
How have you been?
I just wanted to thank you for giving me advice regarding my new job at LS. I know it was your brother's wedding party, and you probably didn't want to talk about work there, but all the advice you gave me was very helpful! I would never talk shop at my brother's wedding! You rock!
Thanks again!
Bob.
