Practice: Some day

1. cannot believe one's eyes / ears
2. in sb's absence
3. judging by / from sth
4. vanish without a trace
5. lock sth away

Some day,
if you vanish without a trace,
you cannot imaging how painful I would.
I will lock my heart away in your absence,
'till you come to open it.
You cannot recognize difference  by judging from my face,
'cause my smile and tear already gone with you.
You cannot believe your eyes,
it seems never change.
Some day you may see,
all the past become weed full of my heart.
