Hotdogs and Sausage

The conversation between the mom and the child goes something like this:
"Nick do you want a hot dog?"
"Is it a sausage?"
"No it is a hot dog."
"Oh I want a sausage" wanders off
5 minutes later...
"Nick do you want a hot dog?"
"Is it a sausage?"
"Well if it wasn't a sausage 5 minutes ago, it is not a sausage now"
"Yeah but does it have sausage stuff inside it"
"No it is a hot dog"
"Yeah but is their sausage stuff in it?"
"Okay Nick if you want it to be a sausage, it is a sausage"
"do you want your hot dog on a roll?"
"you mean my sausage on a roll, yes"
"Mom this sausage is really good"
...and yet we continue to wonder why some mammals eat their young.....
