dear mom, I know you probably think I'm goofing off

Dear Mom:

I know you probably think I'm goofing off, what with this new venture starting out, and already I've logged 5 consecutive days cycling 36 miles each, when I probably should have just been working.

Well, uh, I mean, er uh, what I'm trying to say, um, is, you know ... I'm going to really get serious here in a minute or two. Uh - just blowing off a little steam or something. 

Oh yeah, that's it!  I was working evenings! That's what it is. Really, I mean it.

Don't worry about a thing Mom, you can count on me!
