Just another normal day in family life then, Jingle, eh? My children cross the boundaries every now and then, as do I, and we aren't aways that careful with our rebukes, then feel awful afterwards. But then, when your family is secure enough to withstand that, it happens before you've checked yourself. On another day, you could equally be treading on eggshells and wondering why you have to feel like that. Let it go (sounds like your DD has) and make sure you've got the right glasses next time. She's probably busy sorting out the Bin Weevils subscription, knowing she should have been quicker off the mark.
