Facebook has made it possible for us to wish our friends happy birthday in a variety of different ways; but which one is appropriate for your friendship? How often do you "Like" your friend's status? Never. Whenever they post something I enjoy. Whenever they tag me in it. All the time. Does your friend ever "Poke" you? No, but I Poke them all the time. Only if I Poke first. We have constant Poke wars. How many pictures do you have with your friend? None. Hundreds. Several, they're mostly group photos. Do photobombs count?. How will you know it's your friend's birthday? I marked it on my calander. Facebook will tell me. Another friend will tell me. I found out the date when we were five. Will you be buying your friend a present? No. I might re-gift something. Absolutely. Were you invited to your friend's party? Yes, but I'm not going. No, but I might crash it. Invited? I planned it!. How many mutual friends do you have? Barely any. None. Most of our friends are mutual friends. Tons; and lots of mutual enemies. Has your friend ever shared an ugly photo of you? No. No, but they Liked one. Yes. Does your friend tag you in funny videos? Not very often. All the time!. They send them to me privately. Never. Have you met any of your friend's family? No. Yep, we have BBQs all the time. Only their hot sister/brother.
