Is it wrong/weird/conceited to change your accent?

Why can't you use both?

I am constantly reinventing my dialect. I learnt to speak with the standard home counties accent (educated surrey) but when I went to America I deliberately adopted their local accents as I went (tri-city standard & georgian)

My other Grandmother taught me French in her Parisian dialect but I only ever use it when I'm in that area, I also have family in the Côte d'Azur and they use an completely different dialect all together which I imitate when I'm there.

I'm also learning Spanish, I started to learn with my Mexican friend and I'm now being taught by a Gibraltarian who uses both Llanito and Standard Educated Spanish, they have completely different accents but I use them all depending on who I interact with and where.

I've been to Gibraltar and I use the Llanito, in Cataluna you speak a very polished version of Standard Spanish or you get dirty looks, in Madrid and Analucia you can relax it completely, they use a very different dialect.

You don't have to give up one language or dialect just because you find the need for another, use both when you deem it most suitable. I always use my native accent with my family regardless of where I am or who else is present.

Most Locals can see right through a phoney accent. I try cockney and Irish on people in the US. Although I only know what I've heard from Monty Python, it fools most Americans. I'd never Dare do it in the UK; I'd get dirty looks. In fact, when a Brit talks to me, I revert to a Midwestern Drawl so as not to accidentally mock his accent. But, I say: "Jag-you-arrr"....

I think you should stay true to who you are... however putting on an accent while buying a train ticket might be a bit of a laugh.

Your accent WON'T ever change. (at all)

I don't see anything wrong with it
