Partygoer

[PC_Master]

In Portal, on the achievements list and the achievement: Partygoer, you have to "Make the correct party escort submission position decision."
How do you do that?

LOL, I was amiss to that as well until I found I had not actually completed the game. If all you've done is escape the fire pit at the end of test chamber 19 you are far from done.

Hint: Look up for more promising prospects. The very act of moving onward will get you that achievement.

Yes, I've finished the game, and listened to the song 'Still Alive' at the end, (if fact the second I saw the fire, I knew I would be able to...well do what I had to do (I don't want to give spoilers), but I don't know how do do Partygoer.

[Mr. Matt]

According to my achievements list, I have actually accomplished that achievement, but I'm not entirely sure how. The only thing I can think of is that I crouched down for a short while when the AI told me to assume the party position. If that isn't it, I can't think of anything else that I did differently.

Yeah that's it, after you

Spoiler:

portal away from the fire, and GlaDos start rambling about a party

crouch down (and look to the ground)
than just move on
