And I thought I was alone in experiencing this! My mother tongue is Dutch but I'm fluent in English as well. English is the language I use as soon as I am on my computer or another device (e.g. chatting, internet searches,.. are always in English). Whenever I speak English, it is as though I turn into a person that is more me. I've noticed a few things: 1) I am usually a shy person, but when I speak English the shyness simply isn't there as much and I actually dare to talk about my own personal views and opinions. 2) When speaking English I am more fluent and I can speak with greater clarity. The words just come to me, while in Dutch I get caught up in my words and blackout more easily. 3) I feel as though many things I say or think in Dutch sound really silly, especially when talking about deep subjects such as death and the meaning of life. In English, my opinions about these things somehow just "make sense" or "ring true", while in Dutch I feel like a weirdo, and odd-ball saying silly things that other people might make fun of. 4) In English I dare to speak my opinion more easily, while in Dutch I am much more reluctant to do so (maybe because of point 3). Why is this so? I've contemplated this and in my case I would say that English has become the language in which I am most used to expressing my true self. Moreover, Dutch is the language in which I've encountered the most "resistance" or "disapproval" regarding my thoughts and opinions, and maybe this has caused me to feel uncertain when talking in Dutch and be more "on my toes" in order to avoid disapproval and weird looks. ("Oh gosh what will they think of me!") I am not sure what it is like for other multi linguists, but I have started to think in English and use English for everything on the computer and the internet (which I use a lot). I have many English speaking online friends whom I discuss deep issues with, while this is not something I do frequently with people face-to-face in my mother tongue. Perhaps this is why I am so at ease when speaking English and my true self comes out more, who knows. So I can definitely relate, psulli! Glad to know other people notice this difference too! Would you say you also feel more comfortable when speaking Spanish? Or is the difference simply in the way you interact? Has anyone else experienced anything similar? Feeling more you in a language that isn't your mother tongue? It'd be interesting to hear about it.
