At Nocapes and PreemptiveSalvageEngineer suggestion :)
I still miss my single independant years a little bit ... I had a fair bit of fun, achieved a lot independently and am so proud of my younger self. Although I do wish I could go back to my 16 year old self and give her a slap around the back of the heads and shout 'He's not got hidden depths, hes got hidden shallows! Throw him back!'
I'd also tell her that she's never going to be dainty and pretty, but that she was tall, funny and striking - and that years later that shorter boy that she fancied would be telling her at a school reunion that he actually had a mahoosive crush on her. But was to shy to talk to her. So walk tall and wear those stilettos!
What would you tell your younger self?
