What's that fuzzy stuff ?
The entire floor in my apartment is WHITE ceramic tile and it shows every little bit of dirt. However, when I sweep up, I see lots and lots of "fuzzy/fluffy stuff". Dirt that I may be tracking in, I can understand, but what in the world is that dark grayish color fuzzy/fluffy stuff. It looks like animal hair but I DON"T have a pet. What is it and where is it coming from ????
