— I can not speak from the others. I personally prefer not to call, because I am afraid to disturb people. Everybody has very rich life, and it seems to me I can distract them from something important. Somebody could have dinner with his family, prepare the homework with his children or attend an important meeting. And then all of a sudden his phone rings, but my call could be absolutely unimportant. I may just want to ask: how is it going?
