i do not wear a mask for medical reasons, i have epilepsy, the mask over my face makes me panic, brings on a seizure then i drop to the floor so i am very careful about social distancing to the point i ask people to move back, if they don't in a supermarket queue then i put my trolly behind me...lol, some people get narky about it and my reply is, i have a low immune system and i am recovering from cancer..all true, i am always polite and ask with a smile but
sometimes you need to be blunt, i live on my own and don't always have a choice not to go out and please don't say get an online shop, not practical when i only need veg and milk.
