To get ready for this, I've been wearing my mask throughout the work day even though students are not yet present. I hate it, but I know that I will need to get used to this, and it will be better if I have practiced doing this throughout the day before the students arrive so that I'm not fidgeting with it in front of them. Furthermore, my students do not have a prep period where they can remove their masks, so I've been keeping mine on for the entire work day even when no one else is in the room so I have a better feel for what my students will go through as well. Again, I hate it.
The elastic bands which go behind my ears start to chafe by about lunch time. Meanwhile, the disposable masks that I have been using get clammy through the day, especially the more that I talk. I have to use a mask with a wire at the top as well as keep the top of the mask high up on the bridge of my nose to keep my glasses from fogging up. My face is breaking out more where the mask covers, but thankfully, the mask is covering that. Basically, I hate it.
I would like to get a variety of properly geeky masks, but I haven't found ones that sufficiently fit my tastes, come from a trustworthy source, and aren't too expensive. I'd like to have a sufficient quantity so I can rotate them out as I wash them and so they can coordinate to some degree to what I'm wearing. It looks like I will be just using the disposable ones for the time being. I hate that too.
