In one of my posts (construct a conditional with "where"), a nice answerer gives this example to demonstrate when to use "when" to construct a conditional.
When she looks at me, I get embarrassed
First of all, is it a conditional? The sentence does not seem to fit any of the three patterns in the Cambridge Dictionary tutorial.
Secondly, I suppose that is a conditional and some kind of conditional where "when" is the best choice.
Consider other two possibilities
ex#2 If she looks at me, I get embarrassed
ex#3 Where she looks at me, I get embarrassed
ex#2 sounds unusual, #3 does even more.
That answerer describes this kind of situations this way
"when" could be used, but emphasizing the situation's time occurrence
I guess this is a reasonable explanation. Could someone please gives some other explanations easier to understand? Thanks in advance.
Note: There are 2 questions in here. Please don't ignore the first.
