Monkey Man

I can only guess that you weren't aware of Steve and Dan's friendship; the vast majority here 'though knew very-well that they were super-tight and Dan's passing hit Steve hard.
Just letting you know that you would've caused him untold stress and he would've been biting his tongue when he replied to you.
Lastly, please help me understand why you asked that question in the first place. I mean, he said, "God I miss him", which should tell you all you need to know.
I think some sort of apology is warranted bro'. Thank you.
