I do save voicemails and emails too but rarely use them.

Also, kind of in reverse but I brought a stuffed animal with me to T that was a security object at an age we are having a really hard time with (I was very untrusting and a bit violent at that age). T offered to keep the stuffed animal in his office and has. It is out of sight from other clients in a closet but it is still there. I am not sure what the plan is or how we will use it but I know it is there if I need it.
