No, we're not saving scabs.

Tyce: Mom, can I save this?
Mom: Eew, no, that's a scab.
Tyce: I know it's a scab, it's SO cool! I'll never get another one like it.
Mom: No, we're not saving scabs. They're gross.
Tyce: But Mom, it's small! I can keep it in my pocket! It won't take up any room in the house.
Mom: Why do you want to save it anyway?
Tyce: I want to look at it through my microscope.
Mom: Then look at it and throw it away.
Tyce: But this scab is SO awesome! I want to keep it forever. Can I keep it on my bed? What if I want to look at it again later?
Mom: Then get another scab to look at, but we're not saving scabs.
Tyce: Great idea Mom! I'll just keep growing scabs!
