Translation of waterproof in Spanish

How long have you being teaching Russian and why do you want to learn Spanish? Since when do you learn it? Are you traveling often and if you do in which countries? Are you from Moscow or St. Petersburg?
I usually do not travel, and if I do, then only to England, when I visit my parents who live in a suburb of London. I can not afford to travel too much, because it is a very large expense.
To answer your question I'm a college teacher but I am working now for a real estate agency. I'm also responsible for the finances. It's a very lucrative business but I hate it, most of the time.
