Why are women so stupid?

I've seen so many dumb women. I was talking to a girl the other day and I was telling her how my mother is going to visit me and how I'm worried because I don't have any room for her in my apartment so I'll have to sleep in a couch for 3 days. She asked me if she can come and sleep with me and I'm like "huh, no, you don't have to". Then she says "do you think it's a good idea if I come over?". I was like, "what? No, it's not a good idea at all! I don't want to have sex with you". And she says, "oh, no, I was thinking that maybe we can sleep together". I was like, "nope, you're not coming over. My mother doesn't want you in my apartment". Then she said, "do you want to go out and eat and drink?". I said, "no, I'm tired, I'm going to sleep. We can eat in the morning". She said, "ok", then she started playing music and texting her friend. I'm like, "what?". She said, "no, it's ok. I'm bored and I want to do something". I said, "well, I'm not doing anything right now, I'm tired and I want to sleep". Then she went to sleep. And this was not the first time I saw a woman this stupid. I swear, they're dumber than rocks.
