I've read the posts of several people here.. and somehow the answer
"crust" doesn't make any sense to me at all (no offense meant). ^^"
Anyway, can if be GRAVITY (in relation to "ground"?) I mean, gravity
stops bread's spread... and it's gravity that allows us to tread on
ground. It's just that if you flip it over you shall sing fervid
praises fit for a king is what makes my answer kind of dopey. Laughs.
Anyway, if we don't have gravity, I think we shall sing praises fit for
a king. Think of all the fun we'll have floating in the air (hopefully
not for infinity). Hehe.
