I agree with Miguel'smom. During life transitions, some feel a need to break some friendships. Maybe its fear that an "old friend" would expose past transgressions. FB is all about portraying a certain character. For some that's a goody-two-shoes image, others, a bad-boy/girl image. Some even have multiple FB accounts. I don't know what to think about them! Anyway, think of your true friends and what a blessing they are.
