Sandy, I think it's kind of like what Jackie said. She missed Samson when she was throwing cherries to her kids, because that was an activity that he had been so much a part of.
When you lose a loved one, the pain is huge at first, then it is associated with little things, daily silly things. I think that part is worse, because it catches you off guard. Of course you still miss Barkley. You will miss him for a long time.
He was special and he was a very lucky guy to have a momma who loved him so much.
I'm so sorry you are hurting, it will get better.
