@DeWayfarer Looks like the kind of word I'd get at the spelling bee.

@kentex35 I believe they don't allow compound words though in spelling bees. 🤷🏻‍♂️🙃

Can you imagine just how long each contestant would take just to spell one word? The contest would take all year! 😆

@DeWayfarer well last one I was on was 3rd grade.. that's before they invented dirt.

@kentex35 I am not too far behind you guy! 😊 In six months my age group will change to yours!
