why are couples so mushy and disgusting? Don't tell me it's sour grapes. it's true that they talk and act different around each other. my sister never talks to me that way. i get incredible goosebumps listening to my sister's mushy phone conversations almost every night. to imagine it's only one side i'm hearing and it's already so unbearable. eeks. And i'm always playing the irritating "younger" sister making gagging noises and pretending to throw up whilst she goes on and on. eeks.
