Words cannot begin to express how sorry I am that some Ankles were lovingly squeezed by my comically brilliant but nonetheless sadistic ways.
How could I have known that the pressure that I applied would make you lose complete control? And while it is true that I should not have ventured in the direction of your garter. You must understand that it was all meant in fun. The subsequent carnage that I caused is beyond my ability to express here and I must therefore humbly ask your forgiveness. 
I know that you are perfectly within your rights to spank me but I ask you to think about all the good times we can have if I actually grab both of them at the same time. Just remember that I am first and foremost a possible match should you ever need a bone marrow transplant.
Actually I think that should at least count for a firm grip on both of them.
Sincerely,
LETTER OF APOLOGY
