Light gray queen sheet set with navy piping

I found a light gray queen sheet set with navy piping on a bench outside the Dupont Circle Metro entrance this afternoon around 3:15pm. The set includes a fitted sheet, a flat sheet, and two standard pillowcases; they're clean and neatly folded. The fabric feels soft and breathable, and the tag reads Haven Home. There's a small monogram AM embroidered in dark blue on one pillowcase corner, plus a tiny coffee stain on the flat sheet edge. If this belongs to you, drop me a note with the monogram and Haven Home tag so we can get it back to you.
