As it happens, Willy the White Wolf is on the loose, and it is said that whoever catches him will become rich beyond their wildest dreams (because Willy is magical). When you hear that Willy is in the vicinity, you leave the bench in hopes of catching him. ISOTB.

You see a unicorn and wish to befriend it, so you get up and approach it. ISOTB.

You see the fluffiest, most adorablest (I know what's not a word), and bestest (yes, I know this isn't a word either) doggy in the world that is in a shelter you hurry to adopt it. ISOTB

Your best friend want you to come over and watch 5 Feet Apart featuring Cole Sprouse. You run over there and ISOTB.

You get hungry and want to eat at the local five-star cuisine restaurant, so you leave and ISOTB.

I'd definitely get off the bench for that, 5 feet apart was a good movie.

You get tired and start to sleep on the bench, but get up and go to your house because the bench is uncomfortable. ISOTB.

There is a UFO in the vicinity and it's starting to kidnap random people in the park. You fear for your life and run away. The UFO leaves and ISOTB.

I put a TV on a scooter in front of you and start the movie "Avengers: Endgame." I slowly move the TV away, so you get off the bench to follow the TV. ISOTB.

I start to play 'Whip and Nae Nae' on a bluetooth speaker full volume. You get really annoyed and leave. ISOTB
