I loke shorts too, but I get cold in winter with them. Why do you like them so much?
Because they make me feel free. I have been working from home a lot recently and I wear them 'in secret' nobody on video calls can see me in them.
I can definably see the benefit. I wear shorts when i exercise and they are great.
It can get cold in winter and at times it is too cold to wear them but I think I have around 6 pairs now and as I've got older it's all about comfort for me!
I usually just wear shorts around the house, they make good loungewear.
They do. They are inexpensive too. I get mine online from discount retailers.
How expensive is a decent pair of shorts in your opinion? 
I'd say you should base it on how much you can afford. For longing then perhaps $15 but for a good sturdy pair I'd say no more than $40
What textures of pants? Like what material are good shorts made out of?
Cotton is best for comfort. I like the soft feel of a good pair of cottons. They are also cool in summer.
