I only ever knew Kevin with Jeff.
What I remember most is:

When Kevin came there was a lightness to the air in the house.
There was excitement and joy at the mere talk of his coming.
He lifted the hearts of his family.
There was lots of silliness!

The sparkle in Jeff's eyes was so much brighter when Kevin was there.
They often spoke to each other without words, just using their eyes. (something that annoyed and frustrated me at the time!!)
They were so proud of one another!
They laughed hard and often together...the deep belly laugh of old friends.

My heart is full of the memories and of pain for all his family.
I am deeply saddened and sorry for the loss of Kevin.
