I think if you have "a guy" for certain things your kid will look at you like you're cool. Because you're in the know.
Some people have bike guys, some have guys to help them tear down a house (I have one of those too) and so forth.
But the one that MF cares about right now is the fish guy. And the kid asks me to call him any time we pass the pet store so we can see if the fish are awake.
Miloh will yell up to me, Call the fish guy. And I'll grab my phone... And the conversation will go like this.
Me: Hey fish guy it's Kenny
Me: Yeah, pretty good. You?
Me: I was wondering if the fish are still awake. We'd like to see them.
Me: Oh, they're asleep because it's dark out?
Me: Well tell them MF and I say goodnight.
Me: You too... Bye.
MF: Call the fish guy again
Me: Hey it's me again. Just checking to see if you're sure they're asleep.
Me: They are... Oh but they said goodnight to us before going to sleep?
Me: Maybe we'll stop in later this week... Goodnight.
So the fish guy might not technically be real... But it makes the kid happy that I have a fish guy... So we're going with it.
