Yes, I always feel regret. One thing that I feel regret is because I didn't learn Chinese when I got a free time. Secondly, I feel regret because of didn't really get to know friends, although in short while. That's why, I feel sad when my friends went to other places.
But, I have a wish. I hope I can do my best in learning chinese and also get to know someone.
ps: I didn't know if this a good question. But, I hope that it would be okay.
