I understand that it is currently accepted practice to prohibit children from pointing toy guns at each other. I'm a bad mother so that's not a rule in our house. I generally cite the impossibility of enforcement when other mothers inquire after our deviant practice, but I'm sure there are houses with less lazy mothers wherein the rule is strictly and effectively enforced (including by the prohibition of fake firearms altogether), just as there are houses with five children, a pregnant mother, AND dusted floorboards. Less lazy mothers, I congratulate you. You beat me again.
In keeping with my bad mothering, I was amused rather than horrified to observe that following their initiation to Harry Potter, our children were not content to curse each other with Expelliarmus and Impedimenta and Petrificus Totalis. Our house is unforgivable curse central. Need a door open? Why waste time with Alohomora when you could Avada Kedavra that thing? Cat on the couch, or baby got the Legos you left out? Crucio them both. So I guess all I can say is, if you don't want your kid fake killed by my kid, don't bring him over.
