I'm mad at words..

I've been working on a little short story that I wanted to post for Easter,but It just ain't gonna happen.
I like the premise,and have the ending pretty well nailed,but there is one minor stumbling block that is giving me more than a little angst..

I suck at dialogue!!

If I could tell the story in the narrative,that would be wondermous.Unfortunately,the characters need to interact in order to move the story along,and that's where the whole thing goes to shit.

***Example***

"What's that?" she inquired,.inquiringly.
"Toe fungus!" he exclaimed.
"Oh"...

See what I mean!!

I think it has a lot to do with that fact that I'm just no good at small talk.
Usually,whenever someone attempts to engage me in a conversation that lasts more than a few sentences,my mind starts to move on to other things,and I tend to respond with one of those catch-all conversational bridges.
"Really?...you don't say"..Turns out,..They usually DO say.

In any case,I'll save what I've done so far in "Word",and hopefully present it in some kind of coherent form at a future date.

Still,it doesn't help my fragile ego that even Little Newt is a masterful conversationalist.
This morning,he was playing with a new toy that shoots little foam rubber "disks"..("disks".."masks".."desks"...words that defy proper pronunciation,I don't care who you are!)..Anyway,..he was trying to ask me,"Have you seen my diskesses,..discus,..dis,..that's a hard word!..I think I'll just call 'em CD's"...

Now THAT'S dialogue!
