Asked parents for Labrador but I want a German Shepherd now?

[awindsor1]

Basically i asked my parents for a Labrador but now I want a German Shepherd now?
They have already put a deposit on the Lab but don't know what to say to my parents about it.
Do you think i would be happier with a Labrador anyway?

Also can Labradors be protective as well because the neighborhood I live in is pretty bad.

thanks.
