If you're into winter sports such as skiing or snowboarding then winter could be fun but if you're not into those winter sports then winter can be boring.
I live alone and I'm into any winter sports so winter can be a long boring time for me and the only time I get out of the house during winter is to go to work for 8 hours which is still boring and then come home, browse the internet, read a few books, watch TV or clean house etc and then go to bed.
On some weekends when I don't have to work I sometimes will try to stay in bed under the warm covers almost all day and only get up to use the bathroom or take a shower and eat something.
