At the pizzeria on the 27th of March of 2015, Yaroslav the Ukrainian and I discuss many things. He says that his town in Ukraine is Kharkov (in Russian) or Kharkiv (in Ukrainian). We talk about the palatial subway or train stations in Russia, Uzbekistan, France, etc. Yaroslav's white Canadian neighbour in Vancouver is always drunk, he says, and may have a bit of Native Indian ancestry. We talk about how English slang is not a good habit. Many immigrants here in Canada do not speak slang. Yaroslav still likes learning English. I tell him that when I came to Canada at age 10, I could read English, but I did not speak well. It took me about a year to get accustomed to speaking English.
