Imagine you live near the ocean.
You go to camp on an island, taking a boat each day to and from camp.
One set of grandparents take you sailing.
Your other set of grandparents have a motor boat.
On a visit with those grandparents, you are allowed to drive the motor boat.
Your grandfather has a few lobster traps, and you get to go lobster fishing.
You are also allowed to catch the lobster buoy, and help bring up the lobster trap!
Then!
There are actually lobsters in 2/3 of the traps!
And then, magic of all magic, 1 of the 10 lobsters in the traps is a keeper -big enough to be legal to bring home!
So now, you can imagine your camp lunch contains a bit of lobster salad from that keeper lobster.
Yum!
