Mine was getting a joke in the local language — not just understanding it, actually finding it funny in real time without translating first. Tiny thing, hit me harder than the residency permit ever did.
For me it was the first time I gave someone directions in the street — a stranger asked, and I actually knew the answer. I walked away weirdly close to tears. It wasn't the visa or the flat or the job; it was that tiny moment of belonging. What was the small thing that suddenly made it feel real for you?
