Hi,
Please, why is father in plural in this sentence?

I grew up thinking hard physical work was what fathers usually did.

Thank you in advance,

Hi Kriszta

The plural form of a noun can be used to refer generally to all of the things/people in a certain category. Thus, in your sentence, the word “fathers” refers to all fathers in general.
