I wear 2 hearing aids (usually) even though I have no hearing in my left ear: the left one works on the CROS system, so picks up sounds on my left and sends them to my right ear.
In current times of having to wear face coverings, the mask tapes have a habit of getting entangled with the hearing aids, and pulling them out when I take the mask off.
Last weekend we went for our permitted exercise down to Portobello beach: after a while, “nature called” and I had to go to the public loo: masks must be worn! After coming out and taking mask off, no hearing aid in left ear, so I had to join the queue again, and go back inside and look for it. No sign of it! Re-traced our steps on the Promenade but still nothing found. Back home later: missing hearing aid still sitting on bedside cabinet! Doh, but very relieved to find it!
