If you promised your child he could have a pet rodent as long as he takes good care of it and it doesn’t misbehave. Then your spouse goes to the pet shop with your child and they come home with a capybara.
Obviously you have to move to accommodate the new pet (you can’t disappoint your child by breaking your promise, and you don’t want to get into shalom bayis issues with your spouse) to a house with large lawn (they like to eat fresh grass) and pool (they are semi-aquatic animals). Maybe CTLawyer will let you guys move in- his place sounds ideal. The money he saves on hiring someone to mow his lawn will be in lieu of rent.
