Very Tiring Day

Assalamualaikum everybody..!
I feel very tired today but I do not know why. I've just cycling around the area I live. When I returned, I went to sleep on the bed and my mother forbade me to sleep and she told me to bathe and prayers. After I finished bathing and praying, I feel like going to sleep. So, goodnight all !! hahah... :)
Assalamualaikum ..
