I just brush myself off or change if it matters where Im going.
I went grocery shopping at Sams last week, was sitting down eating a hotdog with the kids when I heard a faint "ting", forgot I had put a threaded needle in the fold of my jeans on my lap so when I moved it fell out. means i went around for hours with a threaded needle in my jeans!
How silly...
I had wondered what I did with that thing before I left.
