If you invite a couple Larsen boys (ok, so they just turned 20 and are anything but boys, but can I call them Larsen boys forever?) over for mocha milkshake experiments, it may not be long before they are on the (deadly, three stories high, requires climbing gear and clipping into the built in hooks) roof helping clean the gutters.
Or maybe they will wear a little girl's jacket on your head and follow the 5 year old around and around and around and around the woods and hills and yard listening to and catching parts of her ramblings and answering questions when you know the answers. Babysitting at its finest.
They may even go to great lengths to entertain little girls, like recalling your grass crown making skills from 3/4 of your life ago.
You may even get to watch them convince your 17 year old to do things that he wouldn't normally do! Peer pressure at its finest.
