It depends. Sometimes I go out and explore new places like I have visited Alexander Garden, Okhotny Ryad, Revolutionary Square, Arbat Street, some shopping centers and a lot of metro stations. At other times, I prefer the coziness of my room and read a book or watch a movie.
The locals have been nice to me. They lend a helping hand and will not let you thank. Conversation is an issue at some times, but translating apps help when English does not.
