Hug someone you care about...
That sounds similar to the protocols at both mine and my wife's work, as well as for both our kids schools. If you have an exposure but are vaccinated there is no action needed other than to monitor for symptoms.
I hear you, there is the off chance your travel could be affected, but you have a very good layer of protection so your chances of even becoming asymptomatically infected are quite low.... especially if you were spaced out with an air purifier. Evidently those are fairly effective if it was the right kind of purifier.
Fingers crossed for you but odds are you will be fine in all ways.
Edit: Obviously I hope your friend is OK.
Friend is vaxxed but has some minor symptoms. He is overly stressed and a workaholic though so it might just be he is run down.
I'm less worried than before and appreciate the good vibes.
