Sometimes I feel sad.

I feel sad because I have so much to share, but no one to share it with.

Would you like to be that person? I swear, it’s not about maths.

Okay, not all of it.

Anyways, I’m teaching a class tomorrow and one more on Thursday. That’ll be the last batch for this school year. Then I’m giving a talk at Cambridge on Tuesday (“You’re walking into the belly of the beast,” says my boss). Whatever, I’ve met the Cantabs. They’re all pushovers. Mostly.

Then again, I never did meet the guy in the wheelchair.

I’m just tired, I guess. I don’t know why I feel so stressed-out all the time. It’s not like I’m writing exams or anything. All this is voluntary.

So I guess the real question is, why am I volunteering?
