The thing annoying me most in life...

I'm a dancer! No - not ballet, not tap, not jazz, not contemporary or hip hop etc... I'm a Ballroom and Latin American dancer (I'm not Latin American). The Dances that I have focused on for the past 2 years are Cha-cha, rumba, Samba, Paso Doble and Jive. I can do a lot more dances, but not as well, because I haven't focused on those dances. Most people have heard of Salsa or Merengue, maybe Bachata within the Latin side of my dancing, and I can do those dances. On the Ballroom side I can do a waltz, foxtrot, basic quickstep... anyway you get the point. I dance!
Well on the 27th of February I have a performance, and it's not some huge thing with a bunch of people... But it's one of my teacher's 50th birthday, and she wanted people from the dance team to dance for her to songs that are meaningful in her life. I will be involved in 3 of these dances. I learned the choreography a little over a week ago and I have it down clean... so that is not my problem!
my problem is that my partner doesn't know the choreography! and my even bigger issue is that he started learning it before I did!!!! I mean, I know we all learn at different speeds, and I know that ever since I was little I've had a knack for picking up things quickly, especially dancing, but it's frustrating you know? So we had pratice yesterday at a studio in St. James and I was on my way there when I got a text from my partner saying "I won't be able to make it today, it's a long story but basically I got 0 hours of sleep. could you fill me in on what we do?" I was MAD! I had gotten mad at him the week before because he didn't seem focused and didn't know the steps and now he was blowing off practice because he didn't get sleep! why didn't he sleep?!?! He knew he had to be at the studio in the morning! Anyway, I went to the studio and the main reason for yesterday's practice was to try to clean things up and get them looking like a dance, not just a bunch of foot-placements at certain times. However, this was difficult for me - because I didn't have a partner. So I danced all my dances on my own - and I nailed the steps! But I knew my partner didn't know them and once I got back to dancing with him, we were bound to mess up! I am dreading this performance on the 27th. We have 2 weeks to get this routine looking clean and he has yet to call or text me to get together to practice to go over what we did yesterday. I am not texting him, it's his responsibility... and if he messes up during the performance, I will continue the dance without him! and it will most likely look better that way...
sorry for the rant... but I figured this was a good place to vent...
