My reply:

Hello ______!

Doppelgangers are nothing to be worried about. They are merely playful elementals who love mimicking humans and putting their physical identities. After shops and restaurants shut down, for example, they love pretending that they are customers, waiters, and salespersons, though only the sensitive can see them. I even recall that, years ago, during a visit to the Malacanang Museum, they lay on the beds and pretended to have sex.

If any person is particularly disturbed about having a doppelganger, he should go to the nearest tree on his property and make an offering of five grains round the base of the tree, or else pour a bottle of inexpensive, red wine in libation on its roots.
