I'm a non-native English speaker and I have a troubling question. What is the difference in terms of usage of "when" and "where"?
"The fact that my action was so embarrassing singled me out to the point [when/where] my friends asked me if I did so on purpose."
"She was angry to the point [where/when] she punched him and broke his pair of glasses."
There is a similar question online:
The word POINT can refer to a place or a time, therefore a relative adverb WHERE or WHEN can be used respectively leading a relative clause as a modifier. However, in Longman, it says WHERE is used whether the word refers to a place or a time, whereas in Oxford, an example clearly shows: We had reached the point when there was no money left. Please help specify. Thanks.
So does this mean we can use the two interchangably?
