I helped my daughter move into her new student apartment today. How's that for surreal?!? I'm very happy for her, she's her own boss from now on and at the same time, I'm quite sad to see her go. It is a little like losing her - very complex and deep; we don't want to go there, just saying...it's surreal.
It doesn't feel that long ago I, myself, moved out... but, let's face it, you don't really get any better reminder of your age when ending a stage in life like this. When your kid move out, you're old. period!
It'll be very difficult Not to worry -_-.
