I see.... I see....
Thanks so much, Englishmaven!!
By the way...
By "sound natural", do you mean the sentence a. and b.?
Or do you also include these two sentences below, too?
***********
c. If a. is written as "off John went down to the ~", is it awkward?
d. If b. is written as "off went John to find the toilet", is it awkward?
