Ik I'm probably exagerrating this entire thing, but as Dawn's real life friend, I believe she needs this right now. You're probably rolling your eyes and going "Oh look, Echo's making a big deal out of this. AGAIN." And I'm sorry if that's what you think, but I suck at arting and I don't really know what else to do to make Dawn feel betterapart from this.
Dawn, Indie may be 17, really old for a dog, but that does NOT prove that she has left this world yet. She is still out in the world. You probably look at Boue every night and think of how much she reminds you of Indie. Cute, kind, big, destructive, smart, loving, caring. No doubt that wherever Indie is in the world, she's thinking about you know, and your family. If this still doesn't help, I'll pray that Indie returns to you someday. I'll get my mum (she's the only one in my family that gets my friends' prayers needs). Heck, I'll even get Lilly to pray. I'll do whatever it takes in my power for you to be reunited with your dog. I've never lost a pet like that, so I wouldn't know how you feel right now, but I will still pray. I will still stay up all night long praying that you find Indie again one day. It doesn't have to be soon, just one day.
