Yesterday I was supposed to handle a conversation in German (ugh, who says I speak German fluently enaugh to do it in the first place...) and acidentally switched to French in the middle of a sentence, not noticing it to the point I was asked what I was saying. I need to go back to German at some point, though "not todaaay" is the only moment I can think of.
Three weeks ago however, I started having fun with Icelandic online. We'll see how long it lasts.
