I used to tell my English students all the time; when confronted with a writing prompt with no clear direction, just start writing anything and usually something comes out of it :)
Love your husband's reaction by the way. haha use your words Dear! :)
That is what I did. The discussion we had when I had asked him for a suggestion was completely crazy. He simple just named off foods that had the word sour in it. I just started writing and we come up with this crazy story LOL .
hahaha yeah, thanks for the help honey, but I'll take it from here !!
