They are very good and very bad at the same time and not conducive to a long and healthy life if you stay around them too long or are there when they twist off.
God, I miss that.
Had a few of those myself. Everytime I think I'm missing it I run through a short mental checklist:
Do I really miss the visits from the Police?
Do I really miss the broken glass?
Do I really miss the trips to the hospital to visit her when the wheels come off?
Do I really miss having to keep bail money around the house?
If the answer to any of them is "no", I decide I don't really miss those days all that much.
Been there, done that, got the t-shirt.
The same lack of inhibition that makes them such "fun" at times, also means that they will do psycho stuff at the least provocation.
