‎Hi! “It's (high) time+pronoun+past verb form” I was talking with a native speaker the other day and he told me we should use infinitive after this expression, but according to the grammar book, we can never use infinitive in this case. Only if we were to say something like: it is time for us to... And I really want to know your opinion. Does it even sound natural? For instance: It's (high) time we bought presents. And also, is "high" often used there, or is it rather an obsolete language structure? It's just that I want to speak correctly in terms of grammar, but I don't want to sound like a dialogue from a grammar textbook…
