Life is life for everyone, hardships are hardships for everyone.

Wether or not a person is suffering the loss of a pet, their second failed marriage, a friend betraying their darkest secret, living paycheck to paycheck meeting the bare minimum of living, trying to feed yourself while living on the streets, or dealing with the local village plague ...

Hardships are hardships. The level of them does not excuse that everyone goes through them and that they are hard for everyone to get through them.

Everyone thusly has the right to "complain" about them.
