In Peru, naturally, we found several differences. Even moving from Nevada to Texas provided other changes. Our move north to Canada has given us more.
My awkward moment came when I arrived at our study group hostess's home. After getting settled in she offered a beverage. I was thirsty, so asked if I could have a cup of tea. There were only tea cups set out, no drinking glasses or pitcher of water. After selecting a tea I enjoy, I waited for my hostess to provide the hot water. But, it didn't come. Definitely a bit disconcerting.
Apparently in Canada (at least here in London) when offered something to drink it is more polite to decline. Filed away for future reference, and a reminder to drink water before arriving. At our break time, she again offered a beverage, which I did receive. Then she had a nice little tray of crackers and cheese, stressing how good the cheese was. Taking her at her word I selected three crackers and three small pieces of cheese. Apparently this was another faux pas!
Slinking back to my seat, I did find the cheese to be wonderful and commented positively. Silence from the other women, a disapproving silence from one. Sigh. Another note: eat before you come, and only take the same as everyone else - which was one cracker and one slice of cheese. Just so you know, the slices were very small, as were the crackers.
I'm learning. But, all I can say is I much prefer Texas hospitality. But, we live in Canada, so now I simply live and learn, remembering to have both my thirst and hunger satisfied before venturing out.
