Why is it so

I know I have to say hi to the sun rise tomorrow.
I know it's that 7.45 bus to catch tomorrow.
I know it would be a busy day tomorrow.
I need a serene and peaceful sleep now...
But
Something is bothering me.....
Something...
Something that I didn't feel when I dine with my family
Something that I didn't feel when I went through Facebook
Something that I didn't feel when I reached my bed
Until
I come across that memory sharing app...............
It made me think...time will change anything...and everything!!
