Oh sure, now I feel like a terrible parent.
My boys genuinely hate each other, fight non-stop, and I count the minutes until one or the other of them leaves the house, even if only for a few hours.
The oldest one technically doesn't live here right now (living with four or five other guys until college starts in September) but he comes home at least one or two nights a week.
If I ever suddenly disappear from these boards, you'll know I had a stroke during one of these visits. One at a time - no problem. Both at home at the same time - shoot me.
I'm starting to get worried. My brother (the one closest in age to me) and I were done hating each other by this age.
