I think as we reach our late teens and early twenties we see our parents differently. It's like any rose tinted spectacles we may have had are lifted and as adults ourselves, we are able to see the flaws in our parents,often for the first time. Personally I think this is quite normal. My mum was a heartless bitch ,but I never really saw it until I hit my mid twenties. I sort of hated her for a few years. OK, not really literally hated her. But resented her in so many different ways and had nothing positive to say or think about her. Then by the time I was heading towards 40 [i'm now 48 ,old fart !!] I can look back [she's been dead for 17 years] and although I still don't like or agree with many things and many of her attitudes and beliefs, I realise she was probably just doing the best she could with her life as she knew it at that moment in time.
