Cooking at home vs eating out vs delivery: what’s your situation?

My boyfriend (20) and I (18) have been living together for 2 years in an urban apartment. For us, it usually goes like this:

1. Delivery
2. Eating out
3. Cooking at home

We visit our parents (and they visit us) often, and they give us lots of home-cooked food. We mostly cook at home just for fun.

I’m curious what it’s like for other people, especially in different age groups or family setups!
