Wear and Tear? Or Not?

[Sam Leon]

Fellow landlords, are the following something you would considered "normal wear and tear" or no?

Window blinds - these blinds were brand new before the tenant moved in 16 months ago. I am not sure what happened but there are some dents on two of the pieces, and some of the nylon strings that holds the blind in place are broken.

Cast iron bath tub - I didn't catch this on the move out inspection, as the tub bottom was very dirty. Once I had the bottom scrubbed and cleaned, I can see scratch marks. Was Wolverine taking bath here? These marks were not present.

Even closer:

No these are not stain or scuff marks, I have already cleaned it thoroughly.
