I miss the mission!

So three different things happened today that made me really ache to be back on the mission again.
As some of you know, I have a few students that I teach Spanish lessons to on the side from my real job. One of my students has her mission call to Peru, and I'm teaching her so that she can have a headstart for when she enters the MTC. This morning we finally got to the point where she knew all the vocabulary and grammar necessary to go through the entire first lesson from Preach My Gospel. As she was teaching me about the restoration and I was pretending to be an investigator, I felt her excitement about soon starting to teach people for real, and her contagious missionary spirit really touched me and made me reflect on how I felt one week before entering the MTC.
Then, on my way to work, I stopped at the International Airport. There was a guy that I met in Rome on my mission, a Brazilian kid named Felipe, who was studying in Rome and who attended the ward I was serving in. I was there when he first arrived in Italy and spoke absolutely no Italian, and I reached out to him and tried my best to talk to him in my broken Portuguese (mainly by guessing words). We became really good friends. Well, he got his mission call to Japan, and today's the day he entered the MTC. I went to the airport along with a few other ex missionaries who knew him from Rome, and we picked him up to take him to the MTC. On our way down, we decided to stop in Salt Lake to eat at a restaurant by Temple Square called the Blue Lemon. Eating, joking, and just being around people who served with me and a member from the mission brought back a special type of nostalgia that I've never felt anywhere else other than mission reunions, and that is impossible to explain.
As we were eating, you'll never guess who we saw eating at the table next to us... My mission president! He was so shocked to see four of his missionaries at the same time who just happened to have picked the same restaurant as him that day! It was so fun talking to him too, and catching up on what he's been up to since he returned from Italy.
Anyways, those three events of today really made me wish that I could go back to the mission. But since I can't, I'll do the next best thing and be the best ex missionary that I can be.
