Using the Present Progressive when describing a situation
You use the progressive when you think about the situation as having a beginning and an end. For example, one person might say, "I live in Toronto" because they don't think about ever leaving Toronto. Another person, pehaps an international student studying at the U of T might say "I'm living in Toronto" because the person intends to leave after graduating. Again, it's not about the facts of the situation, since all situations have beginnings and ends. The speaker uses the progressive to tell the listener how the speaker is thinking about the situation.
