I'm an atheist as well. But I can't prove that I'm right. We can't prove that they're wrong. Live and let live, dude. You're being more thoughtless and more annoying than Jehova Witnesses that don't leave after having asked them to thrice. This is just inconsiderate. @OP: Sorry for your loss. I hope you have a good picture of her somewhere. Preferable with yourself on it as well. I have one of those for all my pets I had and I have them printed out on canvas. That will always help me cherish the memories I've build along with those no longer with us.
