Cheap anniversary ideas? Please help🙏

He has no ideas, and I want to go skating but he doesn’t know how, and since its on the 20th the rink might be packed with holiday parties and stuff(bad bcs covid and both of us get nervous in crowds). It gets really cold where we live, so a picnic at the park we had our first date(before we were official) is out of question. We can’t see a movie because all nearby theaters are closed. We can’t go to each other’s houses because of family stuff. Neither of us can afford going out to eat somewhere fancy.

I don’t know what to do. I wanted to do something special but there’s so many problems and things in the way and I’m out of ideas
