I see her bot as a legacy, Either it slipped off her mind setting it or she did it on purpose before her untimely death.. Then I believe her wishes should be respected!
Such Idea are still welcomed for our kids, this isn't to creep them out but to tell them we are with them even dead!
I hope your mood improves and I believe it is called the situational depression! Hurry and bounce back up, you're a strong woman!!
