“When I am 22, how old will you be?” After some complicated math, we determined that I will be 59 when my son is 22. “Oh good, that means I will be old enough to take care of myself before you die.” Okay… His twin sister had to chime in. “That will never happen.” I didn’t want to ask if she doubts that I will live that long or that her brother will ever be able to take care of himself.
