I Introduce The Selfish Machine

I was woken up the next morning by a loud banging on my door. I groaned and rolled out of the bed. Once I was standing, I realized I wasn't clothed at all. I grabbed a pair of shorts and a a hoodie, then slipped my glasses on since I didn't have enough time to put contacts in. I looked at the bed and realized Tony wasn't there. I stood there for a second, trying to sort out my thoughts. The shower was on, so there was Tony. But what was I doing up...
There was another bang on the door.
Oh, right.
I walked over about two feet and swung the front door open. A lady with long black hair, pale skin and pale green eyes stood there. I almost didn't recognize her.
I squinted. "Mom?"
She gave me a sweet smile. "Hi, Piper Lynn." My mom said, then walked forward to hug me. I stood there, completely shocked. How did she know where I lived?
My mom pulled away, and I just stared at her. I rubbed my face. "Uh, how did you know I lived here?"
"I helped you move in here, remember?"
"Oh, yeah. Sorry."
"It's fine, darling." My mom said, then took a step towards me. "You look just like me when I was 22."
"Thanks." I said softly. I pressed my lips in a line. "Where have you been, mom?"
She shook her head. "You don't want to know that, Piper."
"No, I do. Mom, nobody has seen you in years. You didn't even show up to Leanna's wedding. You're the only parent we have, how can you just disappear like that?"
She sighed. "Can we at least discuss it over coffee?"
"Yeah, fine." I said. I moved out of the way so my mom could come inside. She made a comment about the color of the walls, but I ignored it. She left us. She never told us why. I moved in this studio when I was 19, which was also the last time I saw her.
I poured us two cups of coffee with the pot Tony had already made. Tony's the best, he already had my coffee ready before I was even awake.
Oh, Tony.
"Mom, I actually don't think right now is the best time." I said. I had to get her out before Tony got out of the bathroom.
"What? It was a good time a few minutes ago." She said, sitting on the couch.
"Yes, well I forgot that I have stuff to do today." I helped my mom up from the couch. "Maybe we can have dinner or breakfast, I don't know, text me and-"
"Hey babe, have you seen my underwear?" Tony asked. I turned around to see him only in a towel, which was tied around his waist and bagging a little. My mom glanced over my shoulder and saw Tony.
"Tony, this is my mom. Mom, this is Tony. My boyfriend." I said, followed by a sigh. Tony's eyes grew huge as he stepped forward to shake my mom's hand.
"Oh, Mrs. Kristianson, I am so sorry this is the way I'm meeting you." Tony said.
My mom shook Tony's hand, but was hesitant about it. "Nice to meet you, Tony, but it's not Kristianson anymore. Just call me Karen."
No longer Kristianson? "So you changed your last name back to your maiden name?" I asked.
My mom gave me a sad smile. "Actually, it's Mrs. Cartwright." My mom paused to sigh. "I got remarried, Piper."
I exchanged looks of shock with Tony. I looked at my mother. "Excuse me?"
