Wife isnt working in an office but does that mean she is home watching TV all day? She is working and if she stopped doing her work…that would really mess up your friend’s life.
I think the problem here is that your friend doesnt consider her job as important, stressful or taxing as his.
His job is 10-12 hours a day ONLY.
Her’s is 24 hours…round the clock and the best part is…she doesnt paid nor does she get overtime.
He isnt doing his part.
