When playing any kind of Solitaire card game, if there was a choice I couldn't put a heart on a spade, or a spade on a heart. It always had to be hearts + clubs, and spades + diamonds. This was because hearts were show-offs, and if they got put with a spade they would gloat to diamonds, who really secretly fancied spades and actually deserved to be with a spade because it (diamonds) was a nice unassuming suit. Spades were hunky, Clubs were just gross and smelly. Hearts only deserved to be with Clubs.
I know it's mad but I still do it now and I'm 28.
