Grandpa and Grandma will hug like crazy. Grandpa has been missing Grandma so much.
Grandpa will then scold Grandma for leaving him so long ago. He always told me that she was going to get into big trouble when he saw her again.
There will, of course, be more hugging.
Then Grandma will tell Grandpa to take off his shoes because she has had their mansion clean the whole time she's been in Heaven.
I imagine Grandpa will go find a huge, Heavenly mud puddle to walk through and then to stomp his way into the Heavenly kitchen.
Then, the sweeping will begin. And I know that secretly, Grandma has been missing cleaning up after Grandpa.
This glorious reunion makes the pain a little more bearable. I kept Brent up for an hour this morning after Dad called me to tell him stories about how wonderful Grandpa was and how many fun memories I had with him. My childhood was wonderful in large part to Grandparents like him. Memories for my own safe keeping to come later.
