You are referring to the present. The contraction 's is short for "is." It is like you are saying "What is the weather like?"1) When I ask "What's the weather like?" Am I referring to the past or present?
Does this 's mean was or is?
Yes, all you have to do to make the sentence present is change "was" for "is."2) Another question:
This question "What was it like growing up in São Paulo?" is referring to the past, so how to built [how do you build] this sentence in the present? Is just changing was for is?
