Why does the day go so slow and the evening go by so fast.

Well, maybe the day goes slow because we do a lot of things in the day. We are very occupied in day because of our works.

Hi audienitz! It's because in the morning our body and mind is still fresh and active and the tendency is we can do a lot of things and we can hang on for a long time, not like in the evening where our body and mind is already tired and the tendency is to already take a rest and have a sleep. Aside from that, we normally take the day awake while in the evening, we mostly spend it in sleeping. Have a great day! :)
