Who's On First?

Our cleaning lady came tonight. I was going to just wait until she was done in the kitchen and make supper, but my lovely husband knew I coughed all night and wasn't feeling great, so he came home and volunteered to take the kids out for dinner so I wouldn't have to cook. I thought this sounded great. Of course, we both forgot the part where my kids won't go anywhere without me, so we all went out to Swiss Chalet, which is great, because I still didn't have to cook and I do cherish a special, slavish affection for the Festive Special.
On the way there, we passed an Esso station.
Eve: Mommy, what does E-S-S-O spell?
Me: Esso

Eve: What?
Me: Esso
Eve: No. Not S-O. I said E-S-S-O.
Me: I know. It spells Esso.
Eve: What? How can four letters spell two letters?
Angus: It's a gas station.
Eve: What is?
Angus: The Esso.
Eve (yelling): Why isn't anyone telling me what it spells?
Angus: Oh my god. Are we almost there?

We had a lovely dinner. For dessert, we said the kids would take the M&Ms to go. The waiter gave them two little packs each. Angus took his, I put Eve's in my jacket pocket. We got about halfway home.
Eve: Mommy, can I have my M&Ms? But can you open them?
Me: Okay, I'll just give you one, okay?
Eve: Why? Can't you just open it and give me the whole thing?
Me: I mean one package.
Eve: But can't you just open it and give me the whole thing and I'll take them out one by one?
Matt (snickering): Esso
Eve: S-O? So? So what?
Angus: Oh my God. Are we almost home?
