Wearing Mask Incorrectly...

We have a new aide working with one of our students with CP.  He consistently wears his mask uncovering his nose.  In the good ol' days (ie last month) we had the mask rules all over the place about the 'proper' way to wear a mask and people were encouraged to 'help' each other understand the proper way to wear a mask since it was a requirement for all.  Now that we are mask optional, I don't see the point of trying to get someone to wear the mask properly.  I mean, if he wanted to, he could just take it off.  The teacher, however, is going bananas, and it does irk me when people do this.  I told her, of course she can say something but we can't force him to wear the mask properly so I don't really want to make a big deal of it.  I know we shouldn't assume things, but I feel like anyone who doesn't know the proper way to wear a mask at this point does not want to change their behavior.  

Mostly just venting because it's frustrating.  This is so frustrating and every new twist in this long tortuous pandemic brings a new wave of things to make people crazy.  But I am always interested to hear others views/ experiences with all the crap we go through.
