I did not know B1 personally, but would like to extend my sincerest condolances to his family and friends, both offline and online.
Goodbye, friend,
You are no longer here.
You've given up your worries,
You've nothing left to fear.
We will never forget you,
Or the things you gave.
We take comfort in the memories we have.
So Sleep well, friend,
for we shall meet again.
Some beautiful day,
After the end.
