If someone was old enough to be a single mom by 1985, she's a great-grandmother now, Sean- everyone who was an adult in 1985 is old enough to be a grandparent. Technically, everyone who was alive in 1985 is old enough to be a grandparent. Sean himself is 46, old enough it wouldn't raise any eyebrows if he were a grandpa himself.
Is trooning out the new midlife crisis for guys who can't afford the sports car and couldn't fuck the secretary even if they had a job? Gross. I bet Sean's dad was the only guy on the planet to lie on his deathbed wishing he'd spent more time at work and less time with his son.
