Past tense and present tense in a same sentense. Tense consistent or logically correct?

I am trying to tell a thing that happened in the past. But that thing has a fact that is still true in the present. Could you tell me which one of the following is true?

  1. I had a lesson with a tutor yesterday, and she is a mom of 3 daughters. (Yesterday, I had a lesson with a tutor who is a mom of 3 daughters)
  2. I had a lesson with a tutor yesterday, and she was a mom of 3 daughters. (Yesterday, I had a lesson with a tutor who was a mom of 3 daughters)

My confusion comes from the conflict between tense consistency and a fact. The first pair of sentences make sense to me as the tutor is still a mon of 3 daughters now. The second pair of sentences keep consistent between "had a lesson" and "she was". But I feel it is a bit wrong to use "She was" as it indicates "She is not a mom of 3 daughters now", which is opposed to the fact.


There are no "rules" that you must obey in English: there is only guidance. What follows is guidance.

You are confused by the idea of using the present tense to express "current truths" and using the past tense to give context and background.

If I were writing about the difficulties of a working woman raising children, and I was using her as a current example, I would use “is”. This gives immediacy to the style.

If someone were just discussing things in general and had happened to say, “I’ve got three daughters”, I would use “was” simply to highlight a coincidence – this is background, almost parenthetical information.

None of this is too important; I doubt that native speakers consistently make the distinction between the present and the simple past.
