Married FB couples

Married couples who live together, who meet every day
why do they have to communicate via facebook?
We all believe they live happily together,
why are they stating it officially every day?
(it's true, every single day)
I'm starting to get suspicious.
Is one of them showing off, reminding or demonstrating the territory.
Or don't they remember how to talk the old fashion way..?
Whatever reason, don't write "kisses" to your mate every day,
if you aren't asking for advice on how to exercise it in IRL.
