Is there a phrase meaning that we do not want to talk about something regrettable that we wish to forget?
In italian we say:
stendiamo un velo pietoso
when do not want to talk about something regrettable or embarrassing that we wish to forget.
How can I translate it in english?
You may use the equivalent English expression draw a veil over sth:
If you draw a veil over a particular subject, you do not speak about it because it is unpleasant and you do not want to think about it:
- Yes, well I think we'll just draw a veil over what went on last night.
