What thing you did would you change?

If u culd go back and change one thing you did in your life what would it be? And why?

The thing I would like to change is when I fought with one of my friends before I changed school and moved to another city. I never met her again cos theur whole family went missing after the tsunami. We were really close friends and tho we fought with good reason i always wonder what she remembers of me. I wish we could have said sorry to each other.😛
