If normal just means you get to hug your grandmother who lives an hour away it might be safe right now (in a bunch of countries) or permitted but perhaps unwise (in a lot more countries) and it's likely that for most HN readers it will become a reasonable thing to do around mid-2021.
If it means snogging random strangers at a crowded nightclub after a night of drinking that is safe in a very few places (only a handful of countries with elimination or close enough have "crowded nightclubs" in the first place, those aren't a thing on tiny Pacific islands many of which are COVID free) and legal but unwise in some parts of the world right now but it might not be a reasonable thing to do until late 2021 or after for most of us.
If it means spending a week on safari in some poor country to see exotic wildlife, that likely will not be a reasonable thing to do until at least 2022 and maybe later, it may be technically safe for you earlier, but it probably needlessly exposes the locals to a virus they have yet to receive immunisation for so you shouldn't do it.
