as chance would have it

i have broken more than a few light bulbs in my life. some i have stepped on, particularly the christmas tree lights that always seem to be under foot while wrapping the tree. some i have broken whilst screwing the bulb into the socket. some i have broken while up on a ladder reaching on tiptoes from the second to last rung straining to get the bulb into a staircase fixture. some i have broken opening the package and the bulb drops out unexpectedly. some have broken simply because they were broken in the package when i bought it from the store.

every once in a while i will have the experience where i will step on the light, or screw the bulb in too tight, or drop the bulb whilst up on the ladder, or it will drop from the package unexpectedly...and the bulb will not break...no matter how heavy the step or great the fall.

every time i have a bulb that does not work from the package, no matter what i do with the bulb, it will not work.

there are some guarantees...few actually.
there are many surprises...many actually
