The Number thief 5x.

I was in my own bedroom,
Or was it the den?
I was writing with crayons,

Or was it a pen?
What I remember?
Almost nothing at all!
My parents were out,
They’d gone to the mall,
I was home all-alone,
A drink in my cup,

Hoping the thief,
Wouldn’t show up!
Number thief was,
That small little man,
Who would steal all my numbers,
I wasn’t his fan!
He'd come to my house,
Like 10 times a year,
For the last 5 years,
We'd been living right there... 

How many times had the number thief come to my house in all?
