Or you could just be crazy

Mr. A--- asked me to fedex a large envelope, which wouldn't fit in the fedex envelope. I could only find small and large fedex paks, and it was too small for the latter and too large for the former. (Yay for chiasmus!)

Naturally, I assumed we'd run out of middle-sized paks, so I told Ms. E----, and she went online to order more, but that option wasn't available: only small and large. Naturally, she called fedex and asked why she couldn't order middle-sized paks. Naturally, the answer was obvious: there are no middle-sized paks. Ever. (This paragraph brought to you by anaphora.)
