Remember the Lord, who is great and awesome, and fight for your families, your sons and your daughters, your wives and your homes, (Nehemiah 4:14, NIV)
A beach vacation with all one's family is full of fun and frolic with a little "family feuding" thrown in (think 7 kids ages 13-2)---which is understandable with many under the same roof and "gray-cation" days (Josh dubbed)---days not allowing for much "sun" time.
Feuding topics flow from brother to brother, cousin to cousin, or parent to child.---Nothing major---who gets which scooter, who goes first, I don't need a nap, because I said so, pool-ocean-ocean-pool-pool-ocean, tubby time. Nothing worth a fight.
