SPECIAL BULLETIN: When an individual has a telephone squished to their ear, this is to be taken as a little, red flag that the individual is preoccupied at the moment, and should not be conversated with at that time. Think of this as the opposite of permission to strike up a conversation.
Furthermore, if this individual makes polite eye contact with you whilst she has a telephone squished to her ear, this is nothing more than a gesture of courtesy. It should not be taken as an open invitation to begin dialect.
Yes, God did bless the majority of us with two ears. But contrary to the belief of my next door neighbor, for example, those ears do not work autonomously and should not be treated as such.
