Sis regrets

My sis keep asking why she has not had any dreams of dad, and that dad might not want to see her. I don't see it this way, the reason i kept dreaming about him is probably because i have so much regrets for him, my remorse is much more intense preciesly because i did not do much for him, her insistent on putting dad up at her place regardless of any objections means she has already done all that she can for dad, and she should have no regrets at all.
