Not excited by Pleasant Things?

No fun with tales?
No worry on horrors?
No interest in new things/places/persons?
No expression on shocks?

Reflex action is built-in nature of any living creature. Won’t it be a little bit awkward, if we cannot be excited by some extremely good positive things and cannot enjoy the moment, as others do ?

But don’t worry, if your answers to the above questions are “no”.

There are people who rarely express their feelings. It doesn’t mean that they don’t realise the goodness/badness of the situation. Maybe they are actually not driven by emotions. It is good in one sense as they can take logical decisions, driven by their brain and not by emotions.
