not too hard

[ngamary]

Dear Teachers and friends,

a. What’s the hell is wrong with John these days? He often tries picking a quarrel with me.

b. Honey! Don’t work too hard, I know money is also important, but remember to take care of your health, ok?

c. I really feel very blue when she can’t forget the past and doesn’t forgive me.

- Are these natural?

Thanks

Ngamary

a. What’s the hell is wrong with John these days? He often tries picking a quarrel with me.-- What the hell's. 'To pick' is better.

b. Honey! Don’t work too hard, I know money is also important, but remember to take care of your health, ok? -- Your sentence is a comma-splice; you should have a period or semicolon after 'hard'. The spelling is 'OK' or 'okay'.

c. I really feel very blue when she can’t forget the past and doesn’t forgive me -- 'Blue' is a very old-fashioned word, except in songs. 'Won't' would be more natural than 'doesn't'.
