As a bidet owner, let me tell you that only wiping water to dry yourself is the best way to wipe.

My guess is sympathetic response and adjacent fears (an axe murderer might not attack you, but a fear of a “strange” neighbor could be unnecessarily exacerbated)

Anecdotally, I know a few immigrants that learned English through TV at a later age. If you’re interested, don’t let your age hold you back!
