A helmet and a padded suit?
What do you do when you leave your buddy behind a bush for 2 minutes MAX and you immediately hear a loud thump because somehow they managed to snag your popper fly, go into the water to retrieve it, slip and fall onto their back on the way out, and on top of their reel breaking it to pieces within those 2 quick minutes?
Probably find some other fishing buddies.
Some people shouldn't be unsupervised.
