Question For Single Men or Women: Do You Find It Shocking...?

Do you find it shocking and even annoying how people want to get "all up in your business" when they find out that you're single? And how bad it can get when you let them know that you are actually HAPPY being single? Certain people feel that it's a "choice" to be gay or lesbian, but when you express the fact that even though you're straight, you're happy being by yourself, they feel like it's some kind of life mission to prove you wrong...even (and ESPECIALLY if) they are not involved in a relationship themselves? How do you react? What do you do when people suddenly decide they want to play "Dr. Ruth" with you?
