Exactly, u know that, if we are not around we switch off the phone but we dont say we are not around. And we only answer in bad manners when the guy starts to ask stupid questions, there are many of them When u hear them everyday u get bored...
But it wouldnt be smart beeing unpolite by the phone. Guy do ur homework better next time Anyway we are not offended. If u want to come over u are invited (But we are not around at the moment)
