I have almost forgotten about it until this afternoon that you popped up the question...
W: hey, how long have we know each other alr?
A: 20 years
W: No wonder... come lets celebrate alr :P
A: How to celebrate???
W: Go somewhere to chill out
A: Haha... Hope can find that time
W: haha... me too
Who would have guess that we have known each other for 20 years already. It seems to me that it was just yesterday when I first got to know you. How time has pass us by and now, it has been 20 years since I got to know you.
I have known some others for more than 20 years but you are different. You have become my brother, my best friend, my partner-in-crime (for non-criminal related stuff like playing a joke on our pet sister) and my best helper.
Truly, it has been an amazing experience so far and I am sure that we have a lot longer way to go.
