My closest friend of over 30 years died 5 years ago leaving two teenage girls which I've become close to as a surrogate uncle. I figured no problem as I've raised two good sons that are adults now and have numerous nieces.
Wow - I had no clue about girls at all. My buddy used to bitch about being in a house of all women and I used to dog him for whining. Where ever you are, my brother, forgive me for I knew not what I was dogging about. These two are real Princesses.
I will give the two ladies this though-whenever there is grubby work to be done, they are there. We spent last Saturday repacking bearings on the 18 yr. olds sailboat trailer prior to launching it for the summer. She dug right in and was greasy handed when we were done.
Next job for me - chaperone at the all night graduation party. I hope I can stay awake.

Good luck, Sol. I know some of your pain with the young ladies.
