Why do we go mum about our love toward friends? We just don’t get the same permission to express it as we do for our spouses. Hallmark cards, love letters, and physical touch: in the US, so many earmarks of affection are confined to our spouses, although they need not be. For our significant others, we have anniversaries, Valentine’s Day, and wedding vows to impart our love. For friends, well, there’s International Friendship Day, but no one’s heard of it (it’s July 30).
