I have on most occasions throughout the pandemic, except last summer right after the second jab when I thought everything was finally over (and even then continued to wear them in crowded places).
IIRC I only forgot 2 or 3 times even for solitary walks, and some of those were 5 hours long.
To my ongoing confusion, me talking here about my intention to continue wearing masks beyond the point of it being needed resulted in someone going to my blog and posting a few abusive messages on an unrelated entry: https://kitsunesoftware.wordpress.com/2021/06/14/why-do-some...
Who wears masks outside? That's never been required in the UK.
