Blood is thicker than Water?

I left the home in London when I was about 3 and a half. I can remember the train station like it was yesterday. I was in a pushchair with my Mummy and my new Daddy and my sister was in another pram a big silver cross coach one. We were going to Liverpool which was where Mummy and new Daddy lived in a lovely big flat with a garden.
I was absolutely terrified if the space between the train and the platform and screamed blue murder when they lifted my pushchair to put it on the train, I just knew I was going to fall in the gap and it was going to swallow me up. It didn't of course I was fine and we all arrived in Liverpool safely, but not before a few sharp slaps on my legs for "creating over nothing" that was the first sign that my mother was not perfect.
The flat was a basement flat near Croxteth park it was very dark and didn't smell very nice but the garden was lovely and to a 3 yr old was a huge playground to play in. My mother took me and my sisters to a local dress maker and had us kitted out with pairs of matching dresses, and we had matching shoes and coats etc people thought we were twins as we were practically the same size, but it was my sister who everyone commented on and " Oh it was a shame we weren't identical wasn't it a pity for the plain one?" My mother never corrected anyone who assumed we were twins which looking back was a bit strange. Kinder people would say my sister was bonny now but I would be a looker when I grew into myself but I knew they were just trying to make me feel better.
My Mother was heavily pregnant with my little brother when we moved into a brand new house in the New Town where they where building all the factories and my Dad had got himself a job in the glass works as a fitter/repairman so when i was 4 we move from Liverpool to the New Town.
 I don't know where my Mother and My Dad had gone, I just remember me and my sister were alone in the flat and everything was packed to move, my sister had started to cry and for some reason I decided she must have tummy ache, so I found the "medicine" and gave her some to make her feel better she must have been about 2 and I was just turned 4 she had a few spoonfuls and stopped crying I forgot all about it and mother and dad came back with fish and chips for everyone we were all happily tucking in when my sister started to vomit, I asked mother if I should get some more medicine and all hell broke loose, the bottle was found and it wasnt medecine but furniture polish and I had fed it to my sister, its all a bit of a blur from then, Ambulance hospital doctors etc, my mother laughing with the nurses at what a scamp I was, everything was fine but my sister had to stay in overnight just to be safe.
We got home and into the front door and my mother went mental raining blows all over me swearing and calling me god knows what kind of stupid bitch and everything else, my dad pulled her off and put me to bed and told me not to worry everything would be fine in the morning.
 In the morning I couldn't open my eyes and my mother was crying and saying how sorry she was and she loved me so much it was never going to happen again I was her special little girl her first born and she was so so sorry.
I found out as I was growing up that my mother lies A LOT!
