Soo unprofessional

Here is an excerpt from a recent discusion.

Me: Hey thanks for standing me up. I thought you were an honest person.
Trixy: holy crap, I am sooo sorry, don't hate me, I totally forgot, I am shopping in a different part of town, and I have to meet my sister. Where are you?
Me: well, this is not the first time. At least other times you cancelled in advance. I hope you are not playing with me.
Trixy: No, I never play games, you know that. Lets play it by ear, work in retail has been crazy and we spoke over 4 days ago, I was sick, and I really just forgot. If you don't want to believe me that's just you.
Me: Sadly, cancelling is one of my pet peeves.
Trixy: But if it bothers you I will save you time and stop seeing you. I wil not feed your pet peeves.
I am sure you have better things to do than waiting around for 24 y.o. girls. It was a pleasure meeting you, thank you for your company, and to each his own.
Me: You are 24, I thought you said you are 25, lol u lie too?
Trixy: I am 24, thank you
Me: Dont be mad, I was just trying to be light hearted. Let know if you would like to re-set everything and rechedule.

I got no response

I think I have mentioned this before in other writing, but it seems that so many women under the age of 26 are unreliable to make plans with. I wonder what is the cause of this unprofessionalism. Making plans then cancelling 1 hout before it happens, or not bothering showing up.
And statistically speaking, I have noticed those cases are indeed under the age of 26. I wonder what happens when that number is reached? I have to consult with one of my friends in the medical field.

What do y' all think? I don't think it makes sense to pursue this person...I see it as an interesting and entertaining experiment, however.
