BUGs
I live in Louisana. Here there are a lot of flying bug critters that get into everything. To make a long story short, one day a few years ago I noticed a gnat in my big black cup of coffee. Usually I picked them out then drank. That time I shrugged my shoulders and ignored the gnat. With the coffee grounds and gnat I didn't notice any difference. I've been ignoring the bugs ever since and enjoyed my coffee anyway
