Nothing is going to make up for that kid seeing his dad hoed in public like that, plus it’s gonna be a meme soon enough.
MJ You are not telling truth. That father was a man, and it wasn't worth CRASHING OUT over a damn souvenir
Your reacting is what I expect from a teen. Lets dive a lil deeper tho. So what if he says "Nah fukk that, now step lady

"
She can only do two things, Crash out or continue arguing making the entire stadium be like

which they already was
At that exact moment in time, who was right? I still don't know, did he take it out her hand? IDK, if we go by body language?
The way he casually walked with it.. it felt a lil smug like he did take it out. Either way, some will think he should have it and others would think its hers. If he didn't have his son to give it to, I bet you'd be like "Look at that loser" and if he gave the ball back then?
Then what you are saying would apply, and the Marlins wouldn't have came up with a gift bag for his troubles.
So the lesson, is to show restraint in the face of adversity. His son learned its better not to crash out, be the better person and like minded people will fukk with you. Now if he caught the ball fair and square and there was no scrable in a pile... then he has my permission to sweep the leg. But in this situation, he did the best move at the time imo
