They love each other so darn much. Can you feel the love? After 5 minutes, their behavior digresses. But you can still feel the love, right?
BTW...The slang meaning for cousin is a gullible, innocent person who is easily duped or taken advantage of. Sometimes its difficult to tell which one is gullible, which one is innocent, which one is easily duped, and which one is taken advantage of. Oh well, as the old idiom goes: six of one, a half dozen of the other.
