This precept is practised as part of a set of either 8, 10, or 227 in a monastic context only.
I don't see the point in trying to do it outside of that.
If you are living alone and don't socialise/work much then i guess it would be achievable, but doing what you're doing is only going to give your family the impression that you're rude and/or have gone off the religious deep end.
"Whenever we feel that we are definitely right, so much so that we refuse to open up to anything or anybody else, right there we are wrong. It becomes wrong view. When suffering arises, where does it arise from? The cause is wrong view, the fruit of that being suffering. If it was right view it wouldn't cause suffering." - Ajahn Chah
"Remember you dont meditate to get anything, but to get rid of things. We do it, not with desire, but with letting go. If you want anything, you wont find it." - Ajahn Chah
