Greeklish was my first language; it was only at the age of three that my Mother was advised to stop speaking Greek to me so that I could learn English quicker than I was at the time. What a mistake that was, ach... I picked it back up at 13 and I haven't looked back since. I'm just happy that one of only a handful of schools in the US that offers Greek is only a mile away from me; I've been a consortium student there for three years now.
I was forced to learn Spanish in high school; I say "forced" because my Father thought Ancient Greek/Latin, and French were useless, so he covered my mouth before I could yell "Ancient Greek & Latin!" to the teacher assigned to help me pick my classes the March before I started high school. I resented being forced into a language, so after I served my four years, I purposely let my Spanish slip. Now my good friend got me started on Duolingo to relearn Spanish. We'll see how long I last with this app!
I picked up Portuguese from a teacher at my high school and tried to self-teach myself with a book. I had no one to talk to other than rare passerbies, so it didn't go anywhere. I pick up bits of Ukrainian and Russian at my parish. My Ukrainian priest greets me with "kaliméra, Kosta mou, ti káneis!" and I greet him with "Pryvít, Otče, kak delá!" I keep telling myself to learn Irish, but I haven't learned more than a "cúpla focal" (God, I felt so cheesy writing that). I want to learn Cantonese and I pester a friend of mine all the time to tell me how to say this or that in Cantonese, but all I've retained are the bad things. There was a time in my life when I wanted to learn Turkish and I did try for a few months, but eh. Arabic, too. These days I content myself with picking up Persian from two friends of mine and the professor of my class on Shia Islam. I probably know more Persian than Irish these days: vay Khoda! I also use more Yiddish than you'd think your average Greek American would know, and I've picked up some German from my roommate.
After going through my list, I have come to the conclusion that the thing I lack in life in commitment.
