Graphical user interface, display control device, display method, and program

An information processing system comprising:

• circuitry configured to provide a graphical user interface (GUI) including first and second modes, wherein
• in the first mode a plurality of first content objects are displayed in chronological order,
• the first mode is switched to a second mode based on a selection of one of the first content objects displayed in the first mode, and
• in the second mode
• second content objects corresponding to the selected one of the first content objects displayed in the first mode are displayed,
• the displayed second content objects include one or more of electronic messages transmitted to a person and one or more electronic messages received from the person,
• the one or more of electronic messages transmitted to the person and the one or more electronic messages received from the person are simultaneously displayed, and
• the one or more electronic messages transmitted to the person are displayed so as to be aligned along a first virtual line, and
• the one or more electronic messages received from the person are displayed so as to be aligned along a second virtual line, which is different from the first virtual line and substantially parallel to the first virtual line.
