At times I find myself imaging what Mack would be doing if he were still here, like yesterday at our aunt’s house for dinner. It is not so difficult to picture him playing games on the iPad or watching a program while the adults are talking. But each time I am keenly aware that it becomes harder to imagine. I know the 8, almost 9, year old Mack. I will never know the 10 year old Mack, or the 12, 18 or 22 year old Mack.
