I always thought it was funny when I'd call you on your work line and you'd answer, "This is Mark, may I help you?". Of course you didn't know it was me, but I always giggled about how professional you were. Even when I was calling about something probably silly and trivial (the house was never burning down anyway!), you always answered the same.

The words I miss most are "Hey, Kiddo!".
How I wish I could hear you say those two words to me again.
