CHANGE OF HEART

We are drifting apart
don't know since when

I know we have many differences
It used to be allright
We are different,but we care for each other

No more calls, no more messages
I really miss those
Even...I feel like we are just strangers
who just knew one another for a day

Isn't that sad?
where do our friendship go?
or is it true
people change?
do you have change of heart?
