Boxing for kids

today three of These Younger kids age 11 to 13 and I’m 16 by the way, They took my ball Followed Them and till one of ‘em Said I have a knife and I just Went “you know what just keep the ball” and I Walked off and the kids Were like II was joking and i said “just keep the ball I’m not getting stabbed over a ball” and I Carried on walking then 2 of Those Kids started to come close to hit me and I Turned around didn ‘t do nothing THEY Carried back away and I are walking and then a kid of the cam and just started hitting me (punching me) and i was just calmly Defending my self because It Was not hurting, I Kept while walking back and ET Carried it hitting me and one of the kids got a stick and Threw at me I did not get it and it Fell out my hand so I Carried on walking and walking and then one of my friends saw me, stopped ‘em and cam. So basically what I’m Saying is, did I do the right thing by not punching ‘em or Severely hurting’ em? Im very short 5’4 and They Are Nearly my height I can take all three of ‘em (I do boxing just how to throw punches and defend my self) and I know how to fight, because I did not aim They Are Younger then I Is That The Right Thing to do? Gold Should I Have Them knocked the F U C K out? I’m not ashamed That Were Kids Trying to attack me, I do not care. What If They Came back again should I beat the F out of ‘em? or not? For people so say “your a whimp” why would I want to start with kids? what are you not smart enough and old to know what is right and wrong?
