Did she have a nasaly voice?

Yes, super nerdy and nasally.

One instance, she came to an estate sale with me. I didn't tell I wanted her to go. I invited her and she accepted. So, the way these work is that everyone lines up and then they let people in a few at a time. So, the first people in get the best shit. We get there, and she decides she's not going in. Now, I'm under pressure to not be in there for long because she's waiting for me. I get in line. She's walking around doing nothing. I decide that I need something to put stuff in, so I ask her to get me a box from the car, which is like 15 feet away, so that I don't have to get out of line. "No." I'm like "Are you serious? Please just get me a box, I don't want to get out of line." "No." So, then I have ask the people around me if it's cool that I get out of line to get a box. Shit like that. Later that day, I'm going to all these antique store (this is what I do for a living). She knows I have this shit planned. She didn't have to come. She starts crying about how she never has a day off and now she's wasting it when she has so much important shit that needs to be done. So, I'm forced to leave. We drive the 2-hours back to her place. She gets real high and watches TV for the rest of the night.

That's not even the worst of it, but I felt like it was the easiest one to tell. Shit like that happened every other day. I would pray that she would get high as soon as possible.

Here's a minor one. I had my dog there. She was eating dark chocolate. I said something about making sure my dog didn't get any chocolate. She responded all snarky-like "Yeah, dumbass, everyone knows dogs can't have chocolate." A week later she leaves a package of dark chocolates laying on the floor and my dog eats the entire package. Luckily, my dog is a motherfucking badass and it didn't even phase her (I did call poison control.) Also, FYI, if you ever need to call poison control for a pet, call the human poison control. They have all the necessary info on animals, whereas the animal poison control will try to charge you some outrageous price for a call.

One time I let her hold my dog on a leash, while I went to get us dinner or something. I come back and she's letting my dog roll around on a rotting dead fish.

Only once did I get upset with her, and that time she threatened to call the cops on me. It was over dirty dishes.

I only witnessed how she treated my friend who was there for about a week, and she treated him like shit. She would try talking shit about him to me.
