Lost contact, forever.

There have been a few deaths from my contact list

Acquaintance, not close though
However, it was quite tragic
And unexpected

A father, who always shares his life updates, his family, his work
One last status-doing his job passionately,
The next-just few hours later,
an update of him crashing,
at the side of the road, dead..

The other,
a senior of mine,
was warded for some sudden complication, intubated,
then passed while in his sleep.
Someone who I look up to,
Someone who I went to for some advice,
Passionately sharing his knowledge with others.
Always the first to offer help.
An English teacher,
too.

How will I pass mine, later?
