I feel the need to just drive away in the evening to get me a pizza and watch Netflix alone in the car, it's not that I have no friends but somehow I need that today, is that why I'm weird?
That depends on it. If you are so against other people that you want to be alone all your life, maybe that's not so wise, because you can become depressed in the long run. But if it's not everyday but you just want to be alone for a few days, that's normal.
That's perfectly normal and that's a good thing. People need time for themselves. It would be problematic if you wanted to be alone for the long term.
Haha ne you are not, what is not normal about spending an evening alone with Netflix and Pizza?
I'm also one of the rare species alone in restaurant-goers and movie-goers (alone). Sometimes I just need that.
Is completely normal, every person is individual, everyone needs his break sometimes.
