All these couple that play love on social media, do they say same words to themselves in real life?

Went through instagram this morning and saw quite a number of Nigerian couples sending loving messages to each other for their followers to read. What I wonder now is if these couples look into each other's eyes and say it to themselves when they are alone and no one else can hear what they are saying? Abi, is it only on social media we hear all 'dem cheesy love quotes?' What do you guys think?
