I know how frustrating it is but at least they are letting you get him a friend now. Be calm and patient and it will get here. I know it's hard to wait and I'm sure Gizmo is ready for a friend now but until then just keep giving him all the love and time you can.
BTW....Congratulations on talking to your Dad and convincing them to let you get Gizmo a friend. That was quite a big job and you did it. You should be proud of yourself.
Sometime around the 1st of the year I'm going to looking for your story in the thread...."How I Met My Friend".....okay.
