mirror

my sis noticed fingerprints on the mirror where no one would usually touch. it's at the very top of my full length mirror. the cleaner just came ytd and wiped the entire mirror clean. i didnt notice if she left the fingerprints there, but today the prints are there again. ive been observing ever since my sis mentioned it. the other time the cleaner came, the mirror was clean after they left. the fingerprints are always in a different pattern. a pattern which no one would touch the mirror in. im going to wipe the prints away.

will the prints come back tmr?
