I still have a legitimate accent, but it is weak and getting more “American” each day. When I speak Russian with another Russian, I sound Amerikanskij, even to my own ears. Some of my r’s have lost their rolls, and sometimes, I use an Americanised intonation on several words. While I’ve worked to get rid of the Americanisms, it’s an uphill battle, and I’ve started to learn to be proud to be an American Slav.
Don’t tell me you even stopped drinking!
