Is it acceptable to use the past tense when talking about someone that is still alive but you no longer have any interaction with? "His name was Alex" I always correct myself and use present tense but it feels very weird.
There is a very useful rule which I found in one of video lessons on the Internet, and it turned to be very useful. If you start speaking in present, keep to the present, if you start speaking in the past, keep to the past.It really helps while making sentences. So if you began your story in the past, it would be right to continue in the past. Thus you will avoid a mistake.
