Expressing Appreciation

So, last night I told my husband, "I don't think you appreciate me as much as you should." To which he responded, "You're right, I don't, but I do really appreciate you." To which I then had to respond, "Well, I don't express my appreciation for you, like I should either." And that was that. No tears, no silent treatment, no tantrums...I guess we have now officially been married a long time.
