awkward encounter and the solution is..?

what would you do if you walked in into something and realized that you've been wrongly at the wrong place at the wrong time? kinda like you walk in your bald principal's office while he's putting on his wig, or you walked in on an occupied but unlocked fitting room while the occupant is changing, or you walked in on a friend watching pron stuff or, anything embarrassing!

so what would you do?

1. scream! and run away as fast as you can
2. speechless and expressionless quickly back away, and when its safe run away as fast as you can
3. speechless and expressionless slowly back away, and when its safe run away as fast as you can
4. went "ah! .... ha-ha-ha" with a sorry smile, apologize then back away, and when its safe run away as fast as you can
5. just apologize quickly and then run away as fast as you can
6. confront whatever it is right there right then and expect some explanation, and maybe you could also scold them for doing something thats not right
7. scream and faint (lol)

hum..what else? maybe i can add later XD
so yeah, my option is no. 2! sometimes 4 or 1 (yeah, i'm the "flight" person when it comes to survival instinct XD)

seriously though, being at the wrong place at the wrong time, witnessing something you'd rather not, is certainly not the best feeling in the entire world!
