A hometown can remain part of your language even after it stops being part of your address.

A hometown survives in you as vocabulary, rhythm, humour, and the things you assume without checking. It stays long after you have stopped living there and is often more visible to other people than to you. That persistence is not a failure to move on, it is simply how formation works.

Rather than smoothing it out, notice which parts of it you actually value. Keep those deliberately. What formed you is allowed to remain audible in how you speak.
