I don't think those two words go together very well. It just might be what is called an oxymoron. Bubbles are not known for being logical entities - even though they try.....and try.....and try..... . They like to float aimlessly through time and space, sometimes taking human form, sometimes not.
Certain people call me a "Bubblewoman". That's OK for they see me as I am - part bubble and part woman. Whatever I need to be at whatever time.
Bubbles can see things from a distance, meaning - as we float in the air above the melee that is taking place below - we are more objective in our viewpoints. we are able to see both sides of an argument.
My Bubblemother, a very wise bubble, always says, "There are two sides to every story." My Bubblefather was a great one for diplomacy and tact. He was well respected (that is, for a bubble). Everyone seemed to come to him with their problems and walk away feeling much better.
That is what a bubble strives to do in their time on earth - just make it better. Bubbles love free form flight - just floating through the air, landing randomly on something or someone, touching their lives if only for a brief moment of time. Sometimes they make people laugh and sometimes even cry. (But we don't mean to!)
But bubbles are not perfect. They look perfect with their spherical shape and their glistening surface - but they're not at all. They can at times be extremely fragile - a touch will cause them to burst.
But bubbles can be strong at times too. Just when you think you might have burst a bubble, they will bounce back and surprise you. They must have an inner strength I guess.
But if the worst happens, there is always a new bubble to take it's place. Not perfect. But ready to touch your life somehow.
