Generate a List of Things to Do When You Have Unstructured Free Time and No Ideas

Free time arrives and your mind goes blank. You know you want to do something but you cannot think what, and the options that exist feel either too much effort or too passive. This generates a personalised list based on what you already enjoy, mixed by effort and by solo and social, so there is something suitable regardless of how the time shapes up.

Generate a personalised list of things to do during unstructured free time, based on what I tell you about myself.

The list should:
1. Include a mix of active and passive options
2. Include at least two things I can do alone and two I can do with others
3. Include things that take under 30 minutes and things that take a few hours
4. Avoid anything that requires planning, booking, or spending money unless I have mentioned enjoying that

[describe your interests, what you have been enjoying lately, and what kind of free time this is: a quiet evening, a free afternoon, an unexpected day off]
