I think the point about that was to point out that she (Shimamura) would rather be a loner but she has a meddlesome (loving) family and friends that flock to her without her trying. Basically, she is well equipped to deal with people and does so, but she would rather have nothing to do with people. Adachi is an exception since Shimamura is drawn towards her and actually wants to know more about her and Shimamura doesn't know how to deal with Adachi (because Adachi is totally in love with her). Lastly, she points out that they are opposites because she realizes that Adachi IS a loner but she wants to have more or stronger relationships with people.
