1. Don’t Show Up Empty Handed
If you’re asked to join on a dinner, or even stop by for a visit, don’t show up without anything to offer in return. It’s not always most important what you do bring, but moreso what you don’t. Bringing some chocolates, flowers (no even-numbered flowers, please), or even a toy for the kid is a better idea than to have no idea.
In Russia, hosts usually prepare for their company by offering their best prepared meals and special foods they normally wouldn’t splurge on themselves. If you show up with nothing, it’s a sign that you haven’t a care for the hospitality in the first place.
