I’m sorry, it’s not very exciting but I just don’t understand it.
I have a bedside cabinet, and about 6 weeks ago I noticed that there was some gritty rubbley type stuff on it. I wiped it away but later on there was more there. I thought I mustn’t have cleared it up properly so did it again, more thoroughly.
And basically, ever since, there’s nearly always this gritty stuff there! I can’t imagine where it’s coming from - there’s nothing above the cabinet except the ceiling and a hanging light but they don’t seem to be the source. I never hear it dropping onto the cabinet, or see it dropping, it’s just there!
Where is it coming from?!
