Charles Baxter said this quote

What's agitating about solitude is the inner voice telling you that you should be mated to somebody, that solitude is a mistake. The inner voice doesn't care about who you find. It just keeps pestering you, tormenting you--if you happen to be me--with homecoming queens first, then girls next door, and finally anybody who might be pleased to see you now and then at the dinner table and in bed on occasion. You look up from reading the newspaper and realize that no one loves you, and no one burns for you.
