This is a simple statement - not necessarily an affirming statement/response so the nodding isn't necessarily needed but sometimes might be incorporated for clarity. Signing HERE isn't super neccessary but can add more clarity. If you live elsewhere, you should point towards that place. Such as: ME LIVE (point-to) BURNABY.
Some people might use a rhetorical question instead of this simple statement, which would be: ME LIVE WHERE? VANCOUVER. The WHERE part would be signed with your eyebrows raised to show that it is a rhetorical question and not an actual question. Rhetorical questions can be pretty common in among fluent signers - don't worry about this for now!
