20 meters away, a half-baked person walked towards you, you found each other, how did you walk this 20 meters?

Now let's try to put ourselves in the shoes of this scenario: if you're walking down the road and you find someone you know 20 meters away, but you're not familiar, and he happens to spot you too, and you're pretty sure you're neither blind, you're walking toward him, he's walking toward you.
Then
Here comes the inner drama:
Greetings from afar will be like fools
It would be awkward to walk face-to-face without saying hello
Say hello but don't know what to say next
Don't say hello and don't know where to look
In case I say hello
He pretended not to see it
I'm not very faceless
When I think about it, I can't do it anymore. So I asked my friends for advice.
When I threw this scene to my good friends, one by one the sand sculptures answered that I was about to laugh, come, let's enjoy the methods given by this group of strange people.
Kiyou A: I'll slowly take out my blind crutches. (The other party is thinking: how long has it been since I saw him, this person is already blind, hahaha)
Ji you B: Look left and right, look up and down, pull out my phone, unlock it and put it back, and then smile awkwardly.
Kiyou C: It's not that I blow, as far as my eyesight is concerned, I can't tell if he's male or female 20 meters away.
Kiyou D: Suddenly spit out the food I ate in the morning. (There is already a picture)
Kiyou E: Standing still, the other party will be more embarrassed than you.
Ji You F: Immediately rush to him with lightning speed and cover his ears, and then say hello.
G: Shout out: Are you still alive aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa (My buddy here will die on the spot, hahaha)
But jokes are jokes
When we see oncoming half-baked people
Try not to pretend not to see
It's about summoning courage
Smile and greet each other
After all, a warm smile will melt a lot of embarrassment.
Faced with this embarrassing scene, what would you do if it were you?
