[*] Every time I get an email, from a business or charity I've done business with in the past, with a Subject: that proclaims I should get my dad something, I have this little mental image of leaping through the computer and demanding to be put on a "my father is dead, assholes" marketing exclusion list, preferably with my hands around someone's throat.
Best wishes to fathers of all kinds (especially the non-biological ones), and to all those thinking fondly of fathers today. And strength and support to those for who today's hard, for whatever reason.
