It is in the right part of the forum, but I had to click on a link to read it. You should post (paste) it right below where you wrote: What do you think? For one thing, I can't go back and look at your manuscript to check my memory. Notice that you can go down and read all of the prior thread while you are submitting your reply.
Your comments about "setting up" are valid, but:
If you start off with one of the funny stories FIRST, the reader can be filled in on the "set-up" later. The set-up is called backstory and should be given to the reader during the action. You can't wait to give "the good stuff" later, the reader will have put the book back on the shelf. Start somewhere between the beginning and end of the actual story, not with the backstory. This is called in media res.
Joe Blow knocked and waited, quickly checking to make sure the type of pizza matched the delivery ticket. Yep, pepperoni and mushrooms.
The door opened and Joe nearly fell over.
There stood (the meanest, biggest son of a bitch he'd ever seen) (a gorgeous blond, wearing a shirt unbuttoned nearly down to her waist) (his bitch of an ex-girlfriend, a person he'd hoped never to see again.)
That's an opening. Give your reader credit. Now a reader will assume that Joe was once hired to be a pizza delivery guy, assume he works at a pizza shop that makes pizzas, assume he's either a young guy or an old guy down on his luck, but doesn't need to know which, at this point. The reader will want to know what the person who opened the door is going to do. (the author hopes) If so, you've caught the reader's interest and he'll read on for a bit more.
Some writers tell a person's story from birth. Some start when the character wakes up in the morning, as you did. Almost all beginning writers, including me, started their novels that way. It's a mistake, unless he wakes up in a locked cell or something, but even that's been done so often it's become a cliche.
The opening above introduces conflict almost immediately. Once you've got conflict, your MC must solve it. Voila, you've already got plot in 3 short paras. And it doesn't matter if the conflict is temporary. Once your MC solves the first conflict, give him another one (this is where cliffhangers come in)
Okay, that's enough for one day. Learn the modern tricks of good writing (some older tricks were once good, but they've been overused). An agent or editor won't "wait" for the good stuff, you have to catch his/her interest immediately or your manuscript is rejected.
As for the funny stories about pizza guys, almost everyone at work (Those who know I'm a writer) has told me I should write about the funny shit that happens at our workplace. I won't do it. The funny stuff has to be a side-bar to a real story, something that connects those funny incidents. Some problem (a stutter, impotence, shyness, etc.) that your character must overcome in these delivery encounters, perhaps. A crazy ex-girlfriend stalking him, perhaps. Someone thinks he's a narc informant using pizza delivery as his cover, perhaps. Or maybe just some shadowy figure lurking in the background in all of the (hopefully funny) stories.
Okay, my lunch break is over.
Take care,
