As a poor example: Person A: 'I really liked cats when I was a child.' Person B: 'When you say you "liked cats", could you tell me more?' Person A: 'Blah blah.'
I'm really wondering about the tense of 'when you say' here. Should it be 'When you said'? Is there a name for this type of construction or how the verb 'say' is acting here? I'm falling flat on my face trying to find out. I ran it through a parts of speech tagger and got 'say' as singular present, but that isn't specific enough for me to find usage examples like this.
I understand it'd be 'said' if it was something like 'when you said that, what did you mean?' But how about when the conversation is currently happening?
