Say, you people are clever (which we knew already). I think Brianna and SteveDallas are on the money, especially Steve. I had a whole bunch more clues lined up to trickle out bit by bit. Oh well.

If you're still confused, here's the full explanation:

I'm 36.

6 x 6 = 36, hence it is a square number.

It is also a triangular number:

1
2 3
4 5 6
7 8 9 10
11 12 13 14 15
16 17 18 19 20 21
22 23 24 25 26 27 28
29 30 31 32 33 34 35 36
