We lie about brief trespasses
If we wear a mask 99 out of the 100 times we go out right now, we feel like we shouldn’t have to tell people about that one time we didn’t wear the mask. “I wear masks…” we say. We want credit for those 99 times so we just tell a little lie and say it was 100 times. Just like with condoms, we conveniently forget to mention the one time we weren’t careful.
