You won't be disappointed when all the years you played with the little bastards, feed the assholes and baby-sat the little ungrateful trolls come's to pass. Please don't waste you time like I did, my evil family let their little snott-nosed creeps roam around all day (They were in home school, Mom was working while elder dad kicked the kids out to watch Howard Stern and x-rated movies) so the little freaks showed up after my kids got out of regular school.
Wasting your time on selfish nephews and nieces is insanity, you will discover this once those golems grow up. I believe your family is better off by you spending time with your own kids, don't let your lazy ass family's kids destroy your good days by allowing them to create havoc with your kids. For almost a decade while my evil witch family member was working, her kids we allowed to buzz around like flies, bored, no schooling and now with their inept social skills, relationships are hard for them to keep. Just my warning, I would never waste a second on any JW family member, as Londo posted by Steve Hassan, they will turn quicker on you than a Pakistania Muslim Mob against a Female Christian Woman relief worker!
