-If you have to be a third wheel, I recommend being one with a married couple! At least then you are almost guaranteed that they will feed you! You become like their child! It's wonderful!
-I especially recommend being a third wheel to a couple who is married or been together for a long time...because then they think they know everything about each other! And so you get to be the center of attention:) (if you're in to that...and let's be honest...we all are!)
-If you are traveling, that window seat on the bus or plane becomes yours! Score! (Because couples apparently have to sit by each other and can't be separated for more than 5minutes or people will think they are fighting or something?!)
-You can opt out things and not feel so bad. The con is that usually you get dragged into things anyway because otherwise your "all alone again!"
-you're entitled to being able to duck out of things and be awkward! Because 1.) you're single! All single people are socially awkward! That's why they are single! 2.) the couple lives in their own world! Your presence is like a plant! Pretty and nice, but not necessary...
-watching the couple is very educational...you unintentionally get to learn the dos and don'ts of a relationship!
-you don't have to bother looking good! Own your title baby!
-you get your own bed! Complete with all the sheets and all the covers! It's so nice!
-It makes you aware of just how single you are. You have no one. You will die alone...
-even if another "fourth wheel" comes along, it's usually someone of the same sex. So there isn't even a hope for some eye candy for a few moments. And often times, that person brings a "friend"...so you become the "fifth wheel", which sucks two times more than being a third wheel! :)
-couples share everything! Including finances! Therefore you always end up worrying and spending more than them! And they also share jokes! (Even your jokes...they take them and make them a joke between them...and use them over and over and over again:)
You have to always look away to avoid watching PDA. (Even if they swear they don't do PDA, something happens to them every time they are around you where it just seems like you make them get touchy! I guess this only happens when they are around you though...so feel flattered)
-you eventually have to start asking the couple about their siblings! Even Harry Potter with his freaking magic wand couldn't come up with a love spell to battle the third wheel curse! He totally creeped in on his buds sister. It's inevitable...
Mastering the art of third-wheeling takes patience, a good sense of humor, and most importantly, a genuine love of sitting alone in a roller coaster car for two.
