Well I think the thing I miss the most is the fact that I missed time spent with my family, since my family has a restaurant since I was born my mum had to cook and so on the weekend I was alone most of the time especially when my sister started helping my mum.
I always hated being alone, now too and this fact increased it.
I didn't spend Christmas - my favourite time of the year - or any other national / religious event with my family, the tradition is to invite all the family ( aunts, uncles, cousins, grandparents .. ) during these events but not in mine since my parents were working.
Nevertheless I had a nice childhood, I was happy and I had my little and special moments with my family. Things has changed now I'm older and I have to think to some things on my own, but I like that since it's also part of my personality.
