Many a times, we use the words like 'Haha' and 'Lol' so frivolously that in fact, we don't actually mean it. Sometimes, we use them for the sake of easing up the atmosphere because we're conspicuously majorly tense up on the other side. And maybe to create a facade that we're fine, that everything is alright, that all is well.
Coupled with the fact that the intonation is left to the imgination of the other party, it's easier to mask our true emotions under the ostensible cheerfulness. Probably that is why it's easier to feign everything with the usage of instant messaging and texting, in the absence of any real life communication.
Honestly I've done it many times to others, and I'd ascertain that it's vice versa. We are just afraid of falling under the label of being a nuisance for grumbling too much, and that others might just get sick of it one day. While we want others to open up to us, we find it hard to open up to others.
Perhaps this cumulates to why it is so much more difficult now to really enter someone's life.
I still stand here holding up the roof,
cause it's easier than telling the truth.
