1 - standing
2 - standing, hands behind his back
3 - looking on both sides
8 - first hands behind his back, then scratch his head
9 - after he collided with wall
10 - rotate on 180-degree
11 - 9 and then 8
12 - tired after jogging
14 - like shooting while sitting
15 - amazed
16 - swing arm, like catching a taxi
17 - hands up
19 - talking
21 - sitting
23 - rises
24 - sitting
25 - like he gives something from his pocket then get something
30 - falling
