I always have a little trouble with other people in the house but have slowly been getting over that. What I did first is I would play in another room with the door open so I am still hidden but the sound does come out. Once I have done that I would go into another room so I am playing in different places an settings. Then I will only play a little bit actually in front of another person so it isn’t like a performance and I tell them what I am trying to accomplish so they don’t expect a “song performance” and then I ask for their input so they feel that they are part of the practice. That seems to help me get over the performance part and so far my “person” has been helpful with input as well. Win win situation.
