Life is always full of sudden happenings which struck you all of a sudden without any signal or warning. One person may be healthy and jumpy, but the next moment, this person might just be diagnosed with some kinda incurable disease; one person might be talking to you just a few days ago and all of a sudden, you received the news that he/she had passed away; one person might be talking to you at this moment, and after bidding good-bye to you, he/she might be ramped over by an incoming vehicle while crossing the road over to the other side.
Treasure and love those who are good to you and never leave you no matter what, and always keep in contact even if you're half-universe apart..
Hiro-san, you'll definitely be missed..
