A lot of bilingual children probably couldn't tell you, who they think they are. Firstly, that encompasses the question:
'Where are you from?'
You can find plenty of memes on this topic. But I think at least for myself - I know how to respond now.
My name is Sofia (Cheeky Rose), I am 20 and currently based in Exeter, UK. I am a working student. I juggle working pretty much full-time at KFC and studying full-time towards my degree. I study languages with business. Specifically Russian & Spanish. I barely went to Spain when I was younger for the sole reason of it being a logistical challenge. So, I grew up in Surrey and Sussex. Travelling the majority of the south of the UK - pretty good at driving without a sat-nav now ahaha.
Anyway, that is me in a nutshell.
