Does this happen to you too?

There's always a high probability when I brush my teeth that a glob of toothpaste will fall out of my mouth and into the sink. Why is that? Is my toothbrushing process faulted?

I squeeze toothpaste onto my toothbrush, run the head of the brush under the faucet to get it wet, insert it into my mouth, and then start brushing. In theory, the toothpaste should get scrubbed into a foamy lather against my teeth. But instead, half of the toothpaste falls out as a clump. It makes me feel like I'm waiting toothpaste and it's annoying to scrub off the sink if it dries.

What gives?
