Things you realise when your younger brother comes to stay

My brother who I haven't spent more than a few days together in the last few years has been staying with me for just under 2 weeks. These are the conclusions I have come to...
  1. You revert to being 15 about 5 minutes after he arrives
  2. You start to resent that your brother probably has more friends and more of a life in a city he doesn't even live in than you who has been there for over 3 years
  3. You almost become his mother as you find yourself consistently nagging him for not helping around the house
  4. You actually start to wander if you are an idiot, considering that's how he makes you feel about 80% of the time
  5. And last but not least you will miss him when he goes until he comes back and the cycle starts all over again, he is family after all
