1. Walk into our house with shoes on.
Even kids that just started to walk know this, so there really is no excuse. Shoes are dirty and should not be worn past the hall. If you do, we will give you the death eye, but we are too polite to tell you to take them off. However, don’t expect to be invited to our house ever again.
Don’t even get us started on walking with heels on our wooden floor (yes, we all have them. Carpet is so thirty years ago).
2. Mix up Sweden with Switzerland.
Oh, so you’re really rich, make great chocolate and really expensive watches? No, we don’t. We’re not the home of Toblerone or have a ridiculously strong currency. Get a handle on your basic geography, please.
