Sherlock? Did you manage to get the balloons? -JW
What balloons? -SH
The ones for the party! -JW
What party? -SH
My party Sherlock. -JW
Why are you having a party and why am I not invited? -SH
You'd think that you being such a genius, you would remember things like this. -JW
I do have slightly more important things to worry about. You know. Murders. -SH
I told you about it this morning! It doesn't take that much of your brain power to remember. -JW
You want me to get balloons? -SH
It's my birthday Sherlock. We are having a party tonight. That's why I wanted you to get balloons. -JW
Ah. I'm sorry John. -SH
I'm at the front door anyway. See you in a minute. -SH
... -SH
What is it Sherlock? -JW
SURPRISE. -SH
You remembered? -JW
I would never forget. -SH
