First of all I’m going to show him/her my city. It is really beautiful and it would be so great to share my favorite spot with him/her.
Secondly I would love to introduce him to our culture. It's completely different from theirs, so I hope he will be interested in it. We could watch some old Soviet movies, read books and stuff like that.
And for last I will make him try our food. Like real Russian food. And may be he/she could cook couple of traditional English dishes for us to try. So we can have a international food day. That would be awesome.
I really hope he/she will have the best time ever.
