do you feel ashame if your husband's work is not presentable like other?

I think it depends on how you define "better" or "presentable". As for my husband, he does work in an office, wears office attire and he is called "Sir" or "Boss" and is well respected by both subordinates and peers. Then there's also one i know who dresses raggedly maybe like your husband, gets his hands and clothes greasy yet owns an honest business and gets a bigger income than my husband. In some aspects one has an advantage over the other and vice versa. I am glad that my husband exudes a clean, neat and respectable personality but that doesn't mean that men who do not wear business suits or shiny shoes are not worth presenting anymore. It's what's inside the man, a clean heart and mind, his love for God and how he respects his fellow human beings and the law that matters. If my husband retires or maybe just suddenly change jobs and venture into a business where a suit and necktie become out of place, i would be just a supportive wife, someone he can come home to after a humbling hard day's work.

I think more than being ashamed i would be sad for him, he is not doing it purposefully for me to be ashamed.i dont care for world i care for him. and if his work is not presentable i will love to help him in that. but i dont think for me its a better idea to be ashamed on my husband.
