Packing is like childbirth. You forget how awful it is until you have to do it again.
You get so excited about moving into a bigger place (having a new baby) that you don't think about all the hard work of stowing away your belongings (pushing a 10 pound baby out of a 10 cm hole) can be.

Then the time comes- moving day (day your life alters forever) and you're tired and grumpy and sweaty. Then, you finally get settled in your new, much bigger home (get to hold your child for the first time) and you sigh and think- that wasn't so bad!!
Until the next time.

Side note: Just because I made an analogy between moving and having a baby that does not mean I am pregnant. It does, however, mean I am moving. ;)  Follow the logic?
