OK now I've got your attention with all sorts of wild dirty imaginings I'll get to the point. Do any others here have trouble with annoying little bits of stuff in the feet of your PJs? I find I must turn the legs inside out and shake them every night before putting them on or there is grit in the feet. I have cats and they track litter about the house, it must work through the weave of the feet as I walk around the house. Strange I only notice it the next time I put them on.
Perhaps I need to vacuum more often.
