Isn't that the way with all relationships? People who are closer will be able to adjust to the mood of another person and same dealing with someone who you are not as close with but in a different kind of way. I guess the best way I could think if it right now is not to be offended by a person who is distant but try to find ways to fulfill the relationship to be mutually beneficial without making yourself too vulnerable or creating conflict. sometimes that could mean giving a person space or telling them what you need.
