Types of Couples

I was thinking tonight about life in general, especially after having an entire-day text conversation with a guy I have a little bit of a thing for, and it got me to thinking, and so I decided to come up with a list of couples that I most often see around.
1.The "Just Friends" Couple: This type of couple completely denies being in a relationship, even denying to themselves that it's happening. However, deep down, they and everybody else around them knows it really is a romantic sort of status.
2.The Sea Creature Couple. I call this a sea creature relationship because the pair of them are like octopi or something...they can't help but suck each others' face off every. single. moment of the day. Likely enough, this type of couple is almost always two people you pass by in the hall each day. And everybody else isn't quite cozy with the idea of them publicly making out, despite the fact that it happens each day, no question about it.
3.The Taylor Swift Couple. This is the type of relationship where it's on-and-off, all the time. Basically, this couple is the entire plot of the song, "We Are Never Ever Ever Getting Back Together".
4.The Parent Trap. This is the couple that is constantly telling each other what to do, advising each other what not to do, just like...well, your parents.
