I thought the light in the kitchen was burnt out.
We go to All-American and purchase new lights.
I come back home and plugin the light.
Stacie flips the switch, it does not work.
I try a bulb that I know works.
Stacie flips the switch, it does not work again.
I go back to All-American and buy a new ballast.
I put in said ballast.
Miraculously it works! I feel so proud.

In a totally unrelated case….

Idiot neighbors won’t shut up.
I call police.
An hour later they show up.
