Hi, my son has been invited to a playdate. Because of COVID, this is the first time this has happened as before COVID, he was too young so I would have stayed, then COVID struck, then we would meet with a parent/child outdoors, in a park,etc. My son has been invited to a few birthday parties but that was straight forward as due to the rule of 6, invites explicitly told parents not to stay. Anyhow, I was just wondering what the etiquette is? My son would totally be fine on his own there: he knows this boy and his parents, attended his birthday party and in the past we met up outdoors. I just can't think of a way to ask the question without sounding rude. I don't want to either sound like I don't want to stay, or that I impose...
