Literally just go outside and write ACAB on something. Dumpster dive something. Slack off at work. Map your neighborhood's security cameras. Delete your Instagram. Write a political prisoner. Start a garden. Drop acid. Give a homeless lady some hand-warmers. Put "out of service" signs on parking meters. Pick one and do it right now.
These aren't revolutionary acts, these are the calisthenics you do so you'll be in shape for the revolution.
Why not give them your phone number? You can always block them if they turn out to be weird, and it's a great way of saying "I'm a real person."
Idk, zoomer shit I guess. Also I mentioned that on Instagram you get a small glimpse of a person's life like what friends they have, what they like to do, if they have a job or go to school, etc.
Instagram is still not real life and all of that.
