Oh yeah, this was a very cold winter! Earlier Riga rarely experiences -15.. -20 .. Celsius temperatures. Usually we don't have such cold.
The answer to your question comes by its own. If you can't handle such a frost, then you need a room to spend it

What kind of rooms do we have? Like usually... bars, restaurants, discos...
When I was a student, I preferred smoking at home with my friends

Anyway now I'm busy with the family, and when we don't have to go out, it means a lucky hour.
