I'm a neurodivergent, asocial person. Always have been. Though i still have had a few friends during my life. I managed to get by for a while with just the 2-3 people I talk to, but recently I've started to get really lonely. The way i've made friends in the past has been someone approaching me, not the other way around though. I don't know how to make friends/acquaintances with other people on my own. Me growing up with the internet probably played a role in my lack of real life social skills, i'm guessing
Now I am very sorry. I am so used to people talking like you without sincerity, and I can see that was wrong. I worried that I was too aggro to you after I responded so please forgive me. These are really tumultuous times to still care about the dangers of COVID, even in spaces which should know better. We are critical of the state line in every case but this one, apparently...
An FFP2 should be perfectly acceptable, yes, though I am not totally qualified to give advice about them specifically. From what I know they are equivalent to the N95 grade respirators in the states and those can reportedly be used for several days before they're no longer effective, but they need to be stored in a sealed bag or something similar after being opened. I always play it safe with the disposable respirators when I use them and consider them single-use, at most for the rest of the day, but my similarly-cautious roommate does reuse them for a few days in a row and to my knowledge is fine. I am not sure if the similarities between the standards are enough to recommend this, but I do know FFP2/3 is what you want, and ideally ones with straps that go around your head since the seal with ear straps can be weaker and more easily compromised. No gaps for air to come in or out of any part touching your face when you breathe. It will be an adjustment, but your body will get used to the pace of oxygen; I know marathon runners who wear them every day and still perform.
Aggression is no more or less an appropriate response than "babying" people about these things. I'd say I deserve some aggression for shirking my responsibilities in a way that endangered the lives of others, but even if I had done absolutely nothing wrong, I tend to treat unjust aggression like any other bit of misdelivered mail... Really, I feel like I generally have a particular attitude towards being or doing wrong, which unfortunately does not keep me from either, but which still ends up surprising many people who are used to having to drag people kicking and screaming towards the waters of truth and good, only for them to run off the second they're let go of.
Thank you for your advice.
