Timmy learns about sex

Timmy is five years old and yesterday he witnessed something strange. Today he goes to his mother and asks shyly:
- Mommy, what were you and Daddy doing yesterday?
- Well, Timmy, mommy was about to have a... Timmy, you love ice cream don't you?
- Oh yeah!
- All right. Now imagine you were standing in front of the window of the ice cream truck, and the ice cream man holds out an ice cream cone for you...
Timmy interrupts:
- For free?
- Uh... yes Timmy, for free. Now imagine that ten other kids are eating their ice cream cones near you. It makes you really want to have your own too, doesn't it?
- Yeah, I want ice cream too!
- All right. Now the ice cream man holds your cone very close to you, you can almost touch it. You reach out to grab it, but he pulls it away just a little bit so that you cannot grab it. Meanwhile the other kids standing nearby are licking their ice cream, saying "Hmmmm!" and looking very happy about licking their ice cream. Now you really really want your ice cream cone so you can eat some too. But the ice cream man just moves it in front of you, a little too far, so you can't touch it. The kids are really loving their ice cream, the man keeps your cone too far and you hold out your hand but you can't have it. The kids really love their ice cream and are saying "Hmmm!". The man brings the cone closer to you and you can almost touch it. In fact you can touch the cone with your fingertips! But then he pulls his hand and the ice cream cone back inside the truck, sits at the steering wheel and drives away. That's what was happening to mommy yesterday, and it was when Timmy walked in the room that the ice cream man drove away.
Timmy frowns and thinks about this for a few seconds. Then, in a shaky voice:
- Mommy, did...
- Yes Timmy.
- Did... did Timmmy scare the ice cream man away?
Mommy sighs and says:
- Yes. Yes honey, you did.
