What does these sentence mean? The ceiling of her nursery was blue, with stars in it, as like the sky as they could make it. "But I doubt if ever she saw the real sky with the stars in it, for a reason which I had better mention at once." I couldn't understand "~", especially from for a reason~~~. I think I don't know the special structure of English, do I?

Grammer ? Or differences?? I heard someone said "When would you eat this? " , then I thought why didn't he say that like "When do you eat this? " . What is the difference??

What does mean by this sentence? Probably less so since it's normal over there, though, if I were visiting or something. I don't understand ' less so since', especially.

Probably less so since it's normal over there, though, if I were visiting or something.Also What does 'so ' and ' though' mean and function there?? Just to empathize??
