OK, some new wisdom from the other day!

When your partner is away at a evening meeting at work and you are home tending the childen AND you just have to swing by the store to pick up some bread and milk for breakfast DO NOT under any circumstances allow your 5 year old daughter to help you unlock the door when you get back. Chances are that she will "accidentally" drop the keys through the mail-hatch on the apartment door and thus render you homeless, wandering the streets wearing only t-shirt and slippers with two children until your partners meeting is over and she turns her phone back on and returns.
