So a question about neighborhood kid/son etiquette...

[Saul Good]

What's a round at the batting cages cost? Seems like a trivial amount of money, so the guy's an ass.

Still, you should have given your kid some money. Presuming that the other guy is going to pay for your kid is almost as bad . Even though you have paid for things for his kid before, that doesn't necessarily mean that he "owes" your kid anything in return. If you paid for his kid, you should have done it out of kindness.

If I were that guy, I would have paid, but if I were you, I would have given my kid money just in case.
