For goodness sake!!!
What Treborrobert was trying to say is that some people in this world/country throw their pets out without a second thought to their wellbeing etc.
Treborrobert was using this "statement" if you like to express his feelings with regards to mattymatt123 question, he is a father to this child and so he should act like one rather an irresponsible father (pet owner) and throw his daughter out without a care in the world.
After thinking long and hard about this last night, I have come to a theory (maybe quite incorrectly, and I will stand corrected, if I am wrong) but I think there maybe a new "woman" in mattymmatts life and his daughter doesnt like her and is rebelling, or mattymatt just wants his daughter now out of the way and wants rid of her like a piece of old baggage or in treborroberts analogy, like an unwanted pet.
Stop having a go at treborrobert and start pointing the finger where it should be at, AND THAT IS AT THE FATHER WHO OBVIOUSLY DOESNT CARE A JOT FOR HIS DAUGHTER!
Like I said last night, I just wish my daughter was still alive, so love your children and stop making blasted stupid statements and having ideas of kicking them out!
