Sometimes a simple question or statement can be too invasive for even your closest relationships.
Nurture your relationships. Be sure to avoid harsh words. Be good to each other and don't forget those words of appreciation. According to Dr. Joyce Brothers, "We control fifty percent of a relationship. We influence one hundred percent of it."
To constantly deny fault can make you sound like a whiny child, even to those with whom you have a special relationship.
Why not show your comfort in the relationship and go ahead and assume the responsibility for the mistake or for fixing the problem? Saying something like "What can we do to fix this?" will make your relationship stronger and you will be seen as a more secure person.
Rule of thumb: If you are in doubt about whether you should say something, just don't say it.
Be careful when you asking those in your life what they do all day. You could appear to be accusing them of laziness. Instead say something positive like "You look really busy. Is there anything I can do to help?"
The person you say this to could take it as criticism. Instead, why not approach the situation with a more positive question:
Remember you want to concentrate on helping those with whom you are close, without them feeling chastised.
It could be more helpful to the other person if you tell them you are pulling for them and that you are there to help if they need you.
