I’m towards the end but not quite in the middle- (I have a large family). As a teenager I was also the oldest one home. I enjoyed being the oldest.
One part I didnt like- was Yomtov when my married siblings came home, us single ones were the ones who served, cleared, and cleaned and had to watch my nieces and nephews.(My siblings all felt like they were on vacation when they came home.) Now, I cant say I blame them!
