Considering the Easter Bunny, Santa, and the Tooth Fairy brought my girls the "gift" of joy year after year, I consider them to be very real. My kids are 15 and 18 now and I can honestly say that I have never lied to them. If a pet died, I told them it died. If a family member was going to pass, we prepared them for it. We always had "hot chocolate chats" where we discussed problems, addressed concerns, and answered the hard questions. Tears were often shed during those talks but in the end they grew up knowing I would be honest with them. You can disagree with me if you like but I have two strong young women who I am confident will survive in a challenging world.
Apologies to the OP for getting off subject.
