However, it can also be a double-edged sword because after you know a few different languages, perhaps none of them is perfect anymore. Do you feel the same way?

Oh, yes! Not because I know many languages but because I'm unsure if I know my native language anymore.
Apart from the laughs I may cause, I'm glad I can at least make myself understood (in English). I'm "terribly" glad, haha.

I admire that you prefer to keep going to your old job, even if it means extra effort and expense because you promised and they need you. Of course, there can also be a fear (which I have) of change, and you have to gradually get used to the new reality you live in now.

Your cappuccino is more like a cake...liquid!
My walks are almost always linked to a cappuccino, and I'm glad you adopt this method, too. I like to get together with friends sometimes; otherwise, I only get together with my wife. The discussions are always enjoyable and interesting, as was your discussion. You've already made me hungry for coffee, thank you!
