Thank you for the thoughtful comment, @tressareid. : )
I agree with you, we are all very different and thus more suitable for fulfilling some types of social needs (some people have great sense of humor, some people are very smart, some are very gentle) and less suitable for other (for example, someone can be very gentle but not very communicative, or vice versa).
Thus, we can not expect one person to completely fulfill all of our needs since no one is perfect. :)
