Tourist high season, Spanish anyone?

As the flowers and trees bloom here in Buenos Aires, I am reminded of the beginning of the tourist season here in Buenos Aires. This November has been relatively cold compared with last year, with the air this evening almost like a winter night. I was having dinner with a friend this evening in one of our favorite parrillas, Rio Alba. There was the familar maitre 'd welcoming us and the usual Palermo Nuevo crowd having dinner. The next table was a middle aged German couple having a dinner and speaking very rapidly in a strange dialect, perhaps from Switzerland.
I have noticed recently walking on the streets a lot of foreign languages being spoken. I am sure by the time our hot February comes along, I will long for the damp, cold weather and Spanish only being spoken in the streets. When I first moved to Buenos Aires and I heard people speaking native English, I often wanted to engage them in conversation. Perhaps I was suffering from a mild case of homesickness? Now I find that when I hear English, I want to pretend that I don't understand. I do feel like I am losing some of my English, as I often forget certain words that use to comes easily. As one Argentine friend explained, I am becoming Argentizado or Argentinized quickly!!
