Inner conflict, because I hate outer

How is a person supposed to react when a 'friend' tells you that she wants to hang out with you as long as your kid isn't around her kid. The claim was their age difference (only a year) and that they get each other wound up. Um, news flash- that's what kids generally do when they are put in the same room with each other. At first, I took this request with an OK. Now I feel like taking it with an FU.
The more I think about it the more it pisses me off. Who does this person think they are to make such a request?
I'm not saying my kid is perfect. He's rambunctious, super hero obsessed and full of energy; however, he knows that no means no and when Mommy starts the countdown he better behave and that suitable punishment will be enforced, not just threatened. He is a three year old boy who is constantly complimented on his behavior by strangers in public. He is a good kid.
To not want my kid around is to not want me around. I'm just thinking this person didn't have the balls to say it.
There are many things I would love to say to this person but none of it would be heard, none of it would make a difference and none of it would be very nice. All my words would do is make me even more steamed so I will keep them to myself. I will however not spend another moment with this person and not waste another word on them.
