I did nothing
I didn't do anything special.
I didn't do anything.
I didn't make anything to eat.
Je jure que je n'ai rien fait.
I swear I didn't do anything.
Je n'ai rien fait de la sorte.
I did nothing of the sort.
Je n'ai rien fait pour elle de son vivant.
I did nothing for her while she was alive.
— Voyage à Tokyo (1953)
I haven't done anything immoral.
