Socialising is such an innate need within humans that sometimes, I forget how tiring people can be. They can be so tiring on your nerves, make you feel angry and frustrated, and even ruin your whole day in as little as two seconds.
Sometimes, it feels easier not to have friends, and just rely on your family, no matter how annoying or embarassing or naggy they can be. But when you have issues with your family, friends are the one you go to.
Talk about stuck between a rock and a hard place.
I guess friends are just a necessary evil. Just not all the time.
