I went to dinner with a friend last night and my meal was $22. I go to lunch with coworkers and often only spend ~$15-ish.

One also doesn't need to do activities that cost money in order to hang out with people one knows. Get together and play board games or cards. I hung out with my friends last weekend - we brought our records over and DJ'd, someone brought some frozen burgers, I supplied some THC tincture I've had for months, another person brought a cheap bottle of wine they also already had. We had a blast for like seven hours.

Hiking is also fantastic, and free!
