Wrench and Toothbrush

[ndrosen]

There’s a hardware store a few blocks from my sister’s house, and I bought a wrench there to take home. The reason is that I have an electric toothbrush, and a week or so ago, I tried to change the brush head, but it was impossible to unscrew. I thought I jus5 might manage it with a wrench.

However, the brush attachment doesn’t have the shape of a nut, and trying to turn it with a wrench proved not to work. I may break down and buy another whole Sonic Care toothbrush.
