articulated his feelings about why he feels you shouldn't go, especially since both your 40th and 50th birthdays were a bust. I'm a big believer in celebrating ALL birthdays but milestone ones really should be recognized in a big, BIG way. It would be less frustrating, I'm sure, if Mr. Kris could define his "bad" feeling so maybe it could be worked around.
But if that doesn't happen, then IA with Jenners97. Don't let Mr. Kris' bad feeling affect what you want to do for your big day. And if that means leaving Jack with Mr. Kris while you and a few gal pals, or just you, fly off to London, then so be it. If Mr. Kris has a problem with that...well, that's another problem for another day.
