Train Confusion

I was sleeping when my cellphone rings early in the morning and it was my sister. She was calling me to tell me that she had taken my mom to the hospital.  I don't take any bad news to well so they throw me off, get me nervous and I can't think or stay focused on anything. And the faster I want to do things its like it takes forever.  I said to my sister "I will get dressed and go to the hospital."  She said "ok I will be waiting."  When I finished talking with her I called my other sister right away and to tell her my mom is in the hospital and she said "yes I know I am going to get dressed to go." I told her "I am getting dressed to." She said " so when you finish getting dress call me so that I can meet up with you in the train station."  I said "ok" and hung up. Since I live in the upper section of Manhattan when I take the train its only one stop to her station. I call my sister and tell her "I am ready to go out the door."  She says"what car are you going to be in?" I say " I am going to get on the fourth car." So, great I go downstairs and get to the train station. When I swipe my metro card I see the tv screen and it says 3minutes for the next train to arrive. I sit down and the waited a while for the train to arrive. When the train arrived I stand up and go to the fourth car to see if my sister is there and I don't see her. The door closes and the train takes off.  I look at the tv screen again and it says 5minutes so I sit down and wait for the next train to arrive so that I can get on. When the next train arrive I stand up go to the car and try to spot my sister I say to myself that's weird she's not on. I say to myself maybe she was hungry and stopped by the restaurant to by herself a cup of coffee. I sit down and wait two more trains arrive and people get on and off and I am still in the station. I say what is going on. I take out my cellphone and when I am about to dial her number a phone call comes in and its her. She tells me " where are you? " "I have been waiting here a while and you don't get here" "what's going on?" " Are you in the train station?" "I tell her yes I am in the train station waiting for you" she then says you need to get on the train because you are uptown and I am downtown" and I felt puzzled for a second and then said " oh, yeah yeah, I am getting on now, there's a train about to arrive" she said ok so get on"  When the train arrived since I was so confused I made sure I counted the cars to make sure I see my sister and get on the right car. Since I had wasted so much time waiting for my sister. But in fact she was the one waiting for me. As I wrote this blog I just couldn't stop laughing because its so funny.  By the way my beautiful lovely, wonderful mom is doing well.
