Protocol 24
A series of "protocols" by ~gigog27. A "protocol" is a short text, in which I explain what I would do in a weird situation. The name came from a dream, in which me and some friends were outside, when suddenly one of us shouted "PROTOCOL 24!!!" and everyone immediately started doing something.
Protocol 1
You meet a friend in public, but they don't see that you're with your parents.
There are 2 cases.
Case 1: They can see, but not hear you.
Try to point at your parents (without them noticing), or just interact with them, so your friend notices them.
Case 2: They can see and hear you and start talking to you.
Either address your parents loudly, or talk to the friend and introduce them.
