Once you were with me

Once you were my co-worker
Then you became my best friend
Then you became my support in life
Helping me all through my strive
Your talent and my thinking
We have solved many problems alike
I am so going to miss you
And your super creative solutions too
But wherever you go my friend
My good luck will always stay with you
A final goodbye from me to you
We will always stay in touch and through!
