I applied for a job to a few companies. One place I particularly like. We had an interview that seemed to go well and the interviewer said he was impressed with me. He then sent me an email asking me for my grades from university. I told him that my mother was dying when I was at university and my grades were affected, so I would prefer if he assessed my skills by looking at my portfolio, giving me a test assignment or talking to me.

He said he wanted to see my grades anyway, so I did a stupid thing and didn't reply because I'm ashamed of my grades. A couple weeks later, I got another email from him asking why I hadn't replied. Should I tell him the reason, as stupid as it looks?
