I totaly believe that.. It's kinda like how people do.. I have never had a pet come visit me.. But Family yes.. My Mom tells me they will as long as it doesn't upset you.. Like her Dad will only visit with her once in a while because she cries when he does.. They don't wanna upset you but if your they type like it sounds most of you are then they will visit often because they miss you just as much as you miss them.. I have always believed this.. Maybe I'm just crazy
