When you're single, pretty much everything your friends in relationships do is annoying . . . including stuff that SHOULDN'T be, like posting baby pictures online.  But Babble.com came up with a list of their MOST annoying habits.

#1.)  Too Much PDA. NEW couples are the worst about it.  If you've ever been around two people who just started dating . . . and you were SINGLE . . . you probably wanted to crack their heads together. Get a room...

#2.)  They Use the Word "We" Too Much.  A lot of couples make it seem like they both have the same reaction to EVERYTHING.  As in "WE loved that restaurant" or "WE hated that movie." To single people, the "we" makes you seem like you've completely lost your independence.

#3.)  They Walk Too Slowly.  Any time you see two people walking down the street holding hands, they're always going about 25% slower than everyone else.  It's mostly irritating when you're somewhere crowded, like a mall. Please, just let go and keep moving.

#4.)  They Can't Commit to Anything without Making a Phone Call.  Whether it's a round of golf, or a girls' night out, people in relationships ALWAYS have to run it by the other person. It's kind of like asking your parents for permission.

#5.)  Arguing in Public.  Some couples are worse than others about it, but it's something that annoys pretty much EVERYONE . . . not just single people. No one wants to hear that.
