What they think about us

Here is the British section in Meijers, one of the large supermarket chains. You may be able to make out a number of essential items, including teabags, cornflakes, marmite, oatcakes, baked beans and Yorkie bars. I was so happy to see that jar of marmite!

As well as our culinary habits, Brits (or Europeans in general) are known for their habit of walking where Americans would drive. And for complaining about the heat when for Americans the temperature is just nice. 

I'm not really sure what else they thought about us specifically - perhaps time will tell. They were understanding of our tea habit, though what they'll do with all those tea bags now we've gone is not certain.
