Tina, I hold beverage Left Hand. Now, I will be careful. I used to do it without thinking about it. Left Hand 我左手的拿飲料!

 I yesterday...did something in the tube. Basin, wood basin in the shower room.

Play a white tower in the water, how to use 4 points of the towers to fold, drag, and swipe the edge of all the basin side, like you can see a thing. 

However it swipe 掃到的尾端 都是 perfect touch the edge, or not touching the edge of that wood.

Right to Left, Left to right, front to back, its turn, rotate, ....

well, if they see it..possible they all should be dead....possible.
