If people drink in front of their kids or let them taste alcohol.

I actually have issues about lots of other stuff. I often correct other adults' grammar before realising I've done so (my kids do too actually!) and I would rather get somewhere late than let my kids go out the door with uncombed hair. That drives me NUTS!
Un cut hair though-it boggles my mind when other parents talk about their kids having meltdowns during haircuts. Just.don't.cut.it.
