It's amazing how you can get almost twelve hours of sleep on Friday night and still wake up tired.
Twelve aliyos and a maftir are far too much, even if there is an aufruf in shul.
Learning during Chazaras HaShatz is one thing. Learning during Kedusha, OTOH, is just too far, IMHO.
Children shouldn't eat so much by a kiddush that they can't eat the food their mother prepared for them at home by the meal.
I'm predicting that whereas post-Shabbos learning programs are now one hour in length in the deepest winter, by the time my kids have kids, it'll be two hours, as everyone tries to out-frum everyone else.
