people are lonely
it's sad, but true.
but it is VERY annoying when you can't get off the phone with people... especially when it's your mother. it's not like you want to hurt her feelings, but it's like.... okay.. yup mhmm....
you begin to wonder, "are they talking TO me? or AT me?"
and sadly, it's usually the latter
you should try hanging up once or twice, see if they notice!
