Are boyfriends like bubblegum to us?
When they lose their sweetness we spit them out.
I could never continue to chew on the same piece of gum after the taste had run out.
Or maybe when we're younger, clad in Bubblegummers (as its name so implies), it was all about the sweetness. And now that we've grown up a little, it's about the fun of chewing. At different phases, our purpose(s) switch.
I'd like to think I'm a little more grown up now.
