All right, from my perspective Pleasure and Happiness are completely 2 different entities. They are not at all considered to be equals.
Pleasure is a short term entity which you feel for a second,minute or some shorter period of time.
Like you may find pleasure after a good sex,
you may find it while driving your favourite car/bike,
while having your fav food, visiting your fav place. But al these are temporary or felt for short period and it is felt alone not with group of people involved.
Where as happiness in my point of view is a long term entity or thing you may get it for a longer period of time.
You may be happy around a person you loved, their presence, their talks or even texts can make you happy.
Unlike pleasure, happiness can be felt as group or be with a group of people.
One may find happpiness not by eating fav food but being able to feed many people.
Hope this sufficess for a 20 mark quetion lol.
PS: To all the readers, feel the pleasure, spread the happiness.
Love all,
