If you're only wearing them 'where and when it is mandatory" I would suggest that your thoughts are not for other people, but to avoid police action.
If you are considering others you should wear the mask where it is needed, whether mandatory or not. quote nigel parsons
, i am wearing it where it is needed , but if i am in a car on my own i do not need it.
i make sure i social distance., correctly
wearing masks is not the only important thing . for example i was in a shop the other day with a mask, when somebody came very close to me to get hand sanatiser and brushed against me .,totally ridiculous and destroyed the point of wearing a mask.
i am very particular about social distancing and using hand sanatiser. i suggest that you are making assumptions about my motives and trolling.
