Is it normal that i'm a different person when i speak in english?

It IS normal. You know why? Because a language is more than just a set of sounds used to communicate, it's a whole state of being.

This is even more true for specific dialects. A lot of native English speakers who learn the American dialect for acting, for example, find that they feel more out-going, confident, and casual speaking like an American than they did speaking in their original accent.

You're not an entirely different person, but you might be accessing a part of you you didn't know was there until you gave that part a voice. You just needed the different words, flow, and vibe of the new language to release this "new" you.

In Canada, many francophones learn English, and apparently the ones that also think in English as they speak it, feel differently about themselves when they do. Language is tied to culture, and culture is tied to personal attitude. It makes sense if you really think about it. In fact, I bet the quality or pitch of your voice is also affected when you speak English, maybe even your body language itself.

Okay, now I'm curious as to what's your native tongue and what's your second language. Do tell.

Do you suck cocks when you speak English?
