What's in a name?

Wednesday 13th 2000 @ 1.45am in my nan's living room, watching a movie.

Younger sister: (out of the blue) Why don't people ever call their son Tin.
Saima: Ya what?
Younger sister: Why don't they ever call their sons Tin.
Saima: Because it's not a name maybe?
Younger sister: Well, we have Tim, why not Tin?
Saima: Tim is short for Timothy, what would Tin be short for?
Younger sister: Names don't have to be short for anything.
Saima: Tin is a silly name. It's an object anyway.
Younger sister: So are other names.....
Saima: But it sounds stupid.
Younger sister: All names are stupid. It's just because we've heard them so much we accept them.
Saima: Yeah, let's just make up names left, right and centre. We could have Ton instead of Tom.
Younger sister: Exactly.
(silence)
A character comes into the film called Myron.
Younger sister: What kind of name is that?
Saima: I guess his parents had the same idea as you. Byron just wasn't good enough.
