Ahh family, an amazing dynamic
Is it worth the frustration and ranting for an inexpensive toy, cheap plastic? Non Matterialism wouldn't care, it would be the thought that counted and all that stuff.
Take Johnny's advice sit back and relax, in fact take notes, cause after your children get to be teenagers and you live through that experiance. You too will seek ways of vengence, learn from it. Old age and Treachery beats youth and skill.
Besides Family you can't live with them... and you can't shoot them.
