This post by Ms. Bunny has stuck with me ever since she first wrote it.
"I do not understand people who tell me not to worry about my mother's feelings. Wtf. She is my mother. Do you not realize how much of her life she sacrificed for me? Do they disregard their own parents' feelings? I love my mother even though we don't agree and for me to heartlessly break her heart is not cool in my book. While this whole religion issue causes me tons of stress, I cannot and will not hurt her anymore than I have to."
And that is, in a nutshell, why we spend so much time worrying about our parents and what they think. Yes, you have to be true to yourself - but there is no need to be mean!
