Greetings,
A little kid asked me the difference between
"where did you go for your vacation?"
and
"where did you go in your vacation?"
The sentence with "for" sounds more like what we'd use, but I could not give him a rational explaination as to why the sentence with "for" is preferred, or this is just a peculiarity?
I know this is probably obvious to most of you, but can anyone help me to explain this?
(I told the kid I'll get back to him later arghhh >"<)
Thank you in advance
