Should I argue with my dad about a storm?
Maybe. How does a storm upset you?
With a storm I can't sail my boat.
You shouldn't argue with your dad about something he can't control. A storm happens because of mother nature.
The thing is, he thinks that I should just learn to sail my boat in the storm and is insisting on it.
It doesn't sound like a good idea to follow his advice but you shouldn't argue with him. You can just not tell him what you are doing.
