Some kids might take great joy in studying that there aren't just 
correct times to spit, but additionally occasions when spitting is encouraged.
They might have been instructed sternly at the dinner table that they should keep their saliva, meals and germs firmly 
of their mouth. But someday, a guardian or caretaker 
may encourage them to lustily spit the little black seeds of the watermelon they are consuming onto a plate, into the grass or maybe even at a designated target.
Life is full of surprises. Therein lies the first argument 
towards the seedless watermelon: It takes joy away from children. No, seedless watermelons don't have the sturdy, black seeds of their 
"seeded" counterpart, which many Western watermelon eaters want to spit out though they're 
edible. But they do contain the coatings of those softer, white 
seeds that are merely immature versions of the black seeds.
An even more tragic fact in regards to the seedless watermelon? Those white 
seeds cannot produce extra fruit.
