Let me tell you. you KNOW your sister is cool when, just as the two of you are about to head out for Easter mass, the effects of last night’s drinking force you to run to the bathroom and vomit for ten minutes and her only reaction is to laugh gamely and joke that at least your eye makeup still looks good.

You now she’s even cooler when, as you are trying to control the renegade hangover during mass, she recounts all the instances when you and she have passed out in church, causing you to laugh hysterically throughout the Our Father.
