Depends on the group.

I go climbing with same group at least once a week.

Then I have my big circle of vegan friends, where we try to see each order at least once a month but that can happen more often sometimes.

Then there’s my classic circle of friends I’ve been friends with forever and the same for that, usually once a month.

So even if you disregard my weekly climbing I usually see at least one group of friends every other week but sometimes every week.
