The past

I'm watching Channel 4 about ecstasy.  In the beginning they were talking about good memories coming back, and feelings of euphoria, it made me sad.  Round about 20 I used to go out quite a bit, do whatever, and I remember for the first time in my life really those feelings of complete safety and happiness.  I'd completely forgotten that feeling.  I don't know.  It's not ok to be unhappy really.
