Should i help my father at work? although he is very unpleasant "please read...."?

Aww...maybe you should help him you ne'er know it might make your relationship with him stronger each time...just try to be nice. And if he says anything negative then just ignore him and just mutter uh hu ...try to talk to him about his life and how he was raised and all his background talk about painting...whatever he likes talking about the best just talk to him about.....:) that's my advice hope it helps :)
