Nobody’s perfect, and sometimes you just have to cut people some slack!
Use this idiom within a sentence to say that you should let up sometimes and not be overly critical of what someone does. Sometimes we just need time to learn, or time full stop. Sometimes we just have to accept that mistakes happen, and that they’re not the end of the world.
You can also cut yourself some slack by not always striving for perfection: « good » is good too!
So, all of you English learners, if you’re struggling with the language sometimes and you feel frustrated, cut yourselves some slack! Learning a language is a life long endeavor and certainly won’t happen overnight.
