So it goes like this.....
Me and my mum have finished loading the shopping into the car when she tells me to take the trolley back,yep thats totally normal until I return and see my mum pulling out at her standard snail pace.
I open the car door while its still moving and my little sisters are laughing crazily because I couldnt get in,when I stop for a second and have this amazing vision like im in a movie playing this muscled big dude who is flexing his arms then he turns into Mo Farah and sprints to the car,diving in whilst all the people in the car park are cheering and screaming at him and fireworks start  going up in the air ....

But alas no! Its just little girly me running with my eyes closed! and arms flapping then BANG! my head frickin decides it wants to collide with the roof of the car.Im totally embarassed,tears are comming out my eyes as I slam the door shut begging my mum to get out as fast as she could.

As we head out I just burst out laughing to my mums astonishment  I cant believe how dumb I am and im so confused as to what actually happened because my eyes were shut tight.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Tried jumping into a car,did it with my eyes shut,my head loves the cars roof,ended up with a massive bump on the head,not like in the movies.
