Matt: Hey Layla, how's been your Friday so far?
Layla: Hey Matt, hehe I probably don't know yet. I think I will know tomorrow ;)
Matt: Tomorrow? Goddamit! Why am I so tired like it was Friday? I don't know how to days of the week :P
Layla: Tough week? What racked you?
Matt: Tough year, too much work, not enough sleep...
Matt has had a tough time recently and he's tired.
