I agree with a lot of what Freakie had to say in this thread. On this point, I think there is another side that he may not be seeing.
There is a difference between asking for permission, and asking for acceptance. Just because we all know that Mom accepting the snakes is likely to be slow in coming, if it ever does, doesn't mean Stratus shouldn't let her mom know that she would like that acceptance. The same thing for the fact that whether or not she gets that acceptance, she is going to keep the snakes. It shows that she cares about her mom's feelings, but it doesn't mean that she is willing to let Mom rule her life.
