Happy birthday, Mark!
I've only known you during one of the ten factors of your current age,
but I imagine you brought peace and joy to everyone around you during
the others as well. I feel so lucky to spend every day in your presence
and I look forward to saying I've celebrated three of your factor
birthdays with you when you're twice this age.
Now my question for the
reader --- how old is he?
34 (my age) plus 4 (our difference) plus 10 (your difference).
