So I sent her a nice text back
Hi. I want you to know I was very flattered by your advances yesterday. You are very attractive and if I wasn't married to a wonderful woman I would take you up on your offer in a heart beat. As well, while I am physically fit, I don't believe I would have the stamina to satisfy your needs the way you would like. Best case is I would have to buy Viagra by the drum only to have a stoke when you took your clothes off. You have made me feel 40 years younger and to be honest I still haven't stopped smiling.
