Not objectively/absolutely banal. Relatively more banal, compared to the things people with ADHD can enjoy doing.

(Have you ever seen a crackhead picking at the floor trying to find bits of crack they might have dropped? [A common sight in my city, if you're wondering.] They can do it for 30 minutes with no chance of finding anything, not getting the slightest bit bored. Banal!)
