I just got back from russia the other day, but i have to go back on saturday..

so, i was thinking, there are many cultural things that i am probably not picking up because i wasnt born there. Like here we hold doors open for ladies and it is impolite to point.

what i want to know is what are some differences that i could be doing wrong and not noticing it. I know i would cross my arms while waiting for a crosswalk and people looked at me weirdly... (is this a cultural thing?)

thanks for the help!

P.S. Russia is CrAzY!!!!!!!!!
