How about the old fashioned freezing with a face contorted in fear like your being held at knife point unable to think of anything to say and just waiting to be able to leave? When you get asked a question, fumble over your words and say something stupid. Later on, you can reflexively watch the memory played over and over again so you're even worse the next time. If you see anyone you met during the encounter afterwards, you can just panic and try to hide your face and escape.
That's a lot easier and comes off more natural IMO.
