You've been out of the social loop lately, but you are still on the minds of your friends. They've been reading too much into your silence and think you need time alone. Their perceptions couldn't be further from the truth: you're just busy. Let them know what's up as soon as possible! Get more involved in what's going on outside your individual realm and offer to tag along. Volunteer to help them with household chores to squeeze in some badly needed quality time.
