Good thing to know that I 'd fight extradimensional beings to save my kid . How many parents would do the same ? :P Well , besides everyone I know . ( Except for Matt , cause he IS an extradimensional being .

Answer: It 's just something they 've never thought of before .They 're usually a cold person .They do n't like their kid much .Their kid was n't behaving .
