Trivia! You can make your girlfriend unable to stand up with just one finger

[Director explains]

Now, let me explain to you why you can stop your girlfriend from standing up and hitting you with just one finger.

First, when my girlfriend is sitting, her body's center of gravity is below her spine. When she wants to stand up, she must bend down with her spine, move her body's center of gravity forward, and land on top of her feet to stand up smoothly. When I use my fingers to press her forehead, it will make it difficult for her to move her center of gravity forward, so it is difficult for her to stand up.
If she insists on standing up, she must overcome the huge resistance of her body weight and stand up without moving her center of gravity forward. However, most girls' thigh muscles are not strong enough to do this, so using only the fingers to give a little force to change the center of gravity will prevent her from standing up.
However, the danger of doing this is that you have to keep her pinned to the chair, otherwise once she stands up, the consequences... you can only deal with it yourself!
