yeah that type of stuff is good when a demo is needed visually. sometimes i'll watch someone show a painting technique. we went on a group trip to India in 2014 and my husband and i went off on our own at each location rather than listen to the guide repeating stuff we had read the night before or months before the trip on Wikipedia or in books, etc. we got more photos, interacted more with people, had more fun... while the zombies sat there for an hour listening to a windbag and then had 15 minutes to explore a site (Buddhist sites). 😂🤷♂️😇
