I have seen that in certain places the phrase "remember those times that" is used, when I actually find it more natural to say "remember those times when".
Since I am not a native English speaker I was wondering which is more appropriate.
- "Remember those times that I met Bob" vs "Remember those times when I met Bob".
- "I remember those times that I pretended that I was looking around but I was actually [...]"
- "I remember those times that I would think about [...]"
I found a case in which it sounded more natural to use that: "remember those times that won't come back again", but this is not the same type of sentence.
What do you think? Are these two forms interchangeable?
