1) Clothing Optional.
When I'm at home, I don't have to wear pants or a bra or really...anything. If I want to sit naked on my couch and eat chicken salad, I can do that. If I'm out at a bar or over at a friend's place, I can't do that. And who wants to be out and be restricted by clothes? .... That made me feel like I'm writing a brochure for a nudist colony. But, hear me out, being almost naked at home is usually always better than being out and clothed.
2) No Hair and Make-Up.
The worst part of getting ready for a night out, at least for me, is doing my hair and make-up. It's so boring! I'm all alone in the bathroom with a curling iron and I just have to stand there and my only entertainment is making faces at myself in the mirror. If I stay at home, I don't have to go through that. I can put my hair up in a bun and be done. I don't have to worry if my bangs are done correctly because the television isn't about to judge me. And the best part, at the end of the night, I don't have to wash my face because it's already clean.
Staying at home is much cheaper than going out. Even if you spring for that $6 bottle of wine (Yes. YES.), you've already paid for your entertainment (Netflix, internet bill, cable bill, etc.) and you've already paid for all that food in your freezer (Yeah, I'm talking about the shitty frozen pizzas you got on sale and you hate yourself for liking). Going out requires paying for parking or a cab, paying for overpriced drinks, cover charges, etc. You don't have to worry about any of that at home.
4) No Disappointments.
When you stay at home and rewatch every episode of 30 Rock (Hello last weekend!), you already know what you're getting into. Liz Lemon isn't going to disappoint you (except for this past season, she will then). Your friends will. Things will not go the way you want them to. Someone will cry. Someone might throw up. There will be a fight.
Not with television.
So, don't feel bad about staying home with a bottle of incredibly cheap wine and ignoring the invitations from your friends to go out. You're the one that's having a much better night than they are.
