We see flashbacks of Don's childhood in this superb installment of Mad Men. Don sees a bleak childhood where a hobo identifies his father an one who's untrustworthy. It's no surprise that Don wants to be as detached from this childhood as he can. Conversly, we see how he's having trouble fitting in with the emerging hippie culture he encounters at one of his girlfriends. We are left to wonder how he identifies himself.
Meanwhile Peggy and Campbell do it again in his office, early one morning and Campbell is not just indifferent the rest of the day but is downright curt with both his wife and Peggy. He's another one that's not comfortable with himself.
As i've said before, there is a lot of dysfunction. Great installment.
