Well I remember my first time I got hit with various of kicks to my head (helmet) in WTF TKD tournemants lol
First time I got hit I just went mad and angry kept kicking the shit out of my body and my opponent even when the ref broke up the fight ! I lost my fight but bc of my stupidity and not really knowing the TKD game.
Also when you got hit very hard on your nose is a fucked up feeling first time !
I also got KTFO one time when sparring my TKD buddy for fun (well it was very hard actually) and hit me with spinning back kick (bandae dollyo tchagi) frontal on my face. I only can say you don't feel shit and when you wake up you are like WTF did happen.
When I got hit by highkick on my face, I am totally out for revenge and would like to take revenge for what he did too me.
I don't know that's the right attitude instead of just getting over it and do your job but I am not a pro or wahtever so... My revenge is always over when I can hit him back
The only thing it's a little bit frustrating when you get hit by a highkick on your face by a friend or in competition, but you better get over it and stick on your game and try to sett things right away.
