I have written ” let alone someone”, meaning in my opinion “let him stay alone” , but my friend Hellboy told me that mine is a wrong use , thanks Hellboy 
. However I don’t write here his samples heheheh, I have found another place that teaches
but how can I say ” to leave someone alone” maybe ? Anything else?
Please don’t leave me alone, answer me , thanks !
things to ponder:
1. you didn’t write about letting someone alone, lemme copy-paste your sentence:
CC: she have to look deeply in herself, let religion alone.
translation: She has to think about what she really wants and assess the pros and cons of every decision without considering her religion or religious matters!
and my examples were great, you better say you don’t dare writing them here :LOL:
if i wanna say to someone leave me on my own i simply say: “fuck off me” but eerrrmmm that’s not polite. you can say:
“may i have some privacy!”
and in other words as you have used it yourself it is ” leave someone alone (on his/her own) not LET ALONE!
Abandon
(My favourite usage is in the rather bizzare phrase ‘Frolicking around with gay abandon’…but I don’t know what you’re abandoning in that sense…probably your dignity).
But yeah….You can abandon someone…though it does seem mean. It feels bad when you are abandoned.
You shall not be abandoned.
thank guys
I’m very busy at the moment, but I feel not abandoned when I find comments !
@feelingalittlegay : yes, I was wrong, my brain is pap
