With boys you just never know what you are going to get when you walk in that door after a long day. It's really just a coin flip as to if they will acknowledge your existence, run to you with open arms, or kill your ears with a bunch of crying.
As a person who thrives on routine, the threat of chaos breaking out at a moments notice took some getting used to. You just never realize how much noise and disorder comes with having a child (let alone two) until you find yourself in the eye of the hurricane.
People that live by themselves never have to deal with kids screaming they have to go potty and then never going after 20 minutes of staring at him sitting on the pot. Single people never have the pleasure of hearing two kids duke it out for a spot on a couch that was made to sit three people twice their age. They never have to fight for the remote or hear how it's no fair you get to watch the news before going to work every morning. Single people don't have to deal with crying over too much ice in their cup, too few chips on their plate, and not liking something they just ate last week.
