It is too difficult topic. What is the best thing that has happened to me...

When I was 24 years old, I went to Vancouver, Canada.

I felt a lot of things and It was great influence to me.= I felt a lot of things and it was a great experience to me.



So, I appreciate for the boss of the attending company.= So, I appreciate my the boss in allowing me to go out of the country.

If he did not give the chance, I could not feel some great experience.= If he did not give me the chance, I will not have such a great experience.
