A few weeks ago my family & I went to visit my parents. My parents have a pool that the kids love to play in. But sadly, at the time, one of the boys had both of his arms in casts and therefore could not play in the pool.
To cheer him up, I told him that when his casts came off, I'd bring him back to his grandparents' home & throw him in the pool.
You should always strive to be a man of your word.
