Communication with Different Groups

I think that I do communicate differently with different groups of people due to my comfort level with that group.Take the following as examples:

I am more opened and able to be myself around my twin sister and my very close friends because they truly know me and don't judge me. I can talk to them about anything.
With my husband I have learned that I can not talk to him about politics or sports because know matter what he is going to be right and I'm going to lose the battle.
At work with my residents' I'm kind and soft spoken. I greet each one of them by using Mr. or Mrs. in front of their names to show them respect.
Around a lot of people I'm shy and quiet. I don't really speak unless spoken to, but I also give smiles and say "Hi"
Three strategies that would help me communicate more effectively would be to be more aware of my non-verbal behaviors because my facial expressions could be indicating something total different from what I am trying to say; try not to judge people right off, truly listen to what they have to say and take everything in before responding; and show others respect when communicating. Don't interrupt them, don't be talking to other people while trying to listen to someone else, make eye contact, and make sure you have all the information before responding because if not if could lead to hurt feelings and misunderstandings.
