I grew up always being told "you're not from around here are you" due to having the wrong accent - my parents moved around a lot and when they did settle permanently chose out of area religious or private schools. Parents from different UK countries but no race elements so easier obviously than encountering racism! However I still felt like an outsider, always, except at boarding school and university where everyone is from all over the place.
I hated it and felt awkward growing up. I never felt at home or at ease in the local area where my parents lived, the way I did at school and university. I never thought of the area my parents lived in as home, just of the actual house til I left school, and once at university I didn't feel that I had a"home town" really, and generally didn't go back for more than a few days but spent my holidays in my university town or abroad.
Tbh its who I am and I'm okay with it now. I think of it as a strength in many ways - absolutely no issues with moving to where the opportunities were work and adventure wise as a young adult - able to embrace opportunities, live in different countries and regions and not remotely tied down. That dominoed into making me very independent - never lived near extended family so never had or expected any help at all raising my own children.
My mother has become interested in family history in retirement but growing up I didn't really learn anything about the places my parents grew up - neither of which we ever lived in.
I've unintentionally but almost inevitably but the same very mixed blessing on my own children by marrying a man from a different country entirely. I say inevitably because the idea of ending up permanently with someone very rooted in the area I grew up seems outlandishly unlikely to me - the cultural differences would ironically have felt greater than with someone from a different country but also without the very "local" tied to one place mindset.
My husband also has parents from two different countries and grew up in a region of one of those countries but a region neither of his parents came from. We live in his country and the children are fully bilingual and genuinely don't have a "foreign" accent in either language, though their English is my English so they would stand out as "other" in the UK for not using current teen slang and having a fairly generic international English type of accent.
In the country we live in they have a local accent and people don't realise that they are anything other than local. They've lived here all their lives and know a lot of people when they're out and about. So they are more "mixed" than me but don't get the "you're not from around here" - in fact they are identifiable as from a specific fairly local area.
Despite the freedom of not being tied to a place I deliberately chose to embed my children in the local area, use only local schools and not move them around - I knew very clearly I wanted them to have roots.
Its a mixed blessing even without looking "different" (obviously that's a huge added factor) - but it can be a blessing because it can open up opportunities and make life richer and bring freedom IMO.
