Of course it was gum.  Sweet gummy delicious gum.  I do believe if we had it, we had to flush it when we were done instead of just throwing it away, and it usually had to be wrapped in a tissue.  I remember Mom’s chagrin when Dalin bought us a tub of Dubble Bubble from Goat Savers (as he liked to call it).  We were thrilled (me and Bethani), naturally, and stuffed as many wads of gum in our mouths as we could fit, because you had to get a new piece when the flavor ran out, right?
