As an effect of living alone I would prefer watch movies or even TV alone. I am more confident. I take longer to get ready. And treasure long phone calls with friends who are far. But to be fair I also probably eat more, dance worse (no one's watching).
I think it is something that is undervalued these days. I know girlfriends who have never done it and while I am sure they are happy, I think there is something to be said for being thrust into a new and uncomfortable position and having to rise to the occasion. Be your own entertainment, and become a person of substance.
Another effect of living alone. I will be so thankful to have a male roommate one day soon... Because then he can lift all the heavy stuff, get the bowls that I never use off the top shelf and screw all the screws into the wall to hang curtains and shelves.
