No, I spit mine out.
Other then ‘stones’ like plums, peaches and nectarines, I don’t think I have ever spat out a seed. Why bother? A bit of crunch in a watermelon/grape/apple/pear vs spitting almost every bite? No contest.
Am I the only one who never spat out chewing/bubble gum? I have always swallowed it…the rebel in me is waiting for The Bad Thing to happen.
