#13 Get well soon!
Well, you call this optimism? I call it INSANITY!

#12 She's dead, so dead!!
This level of optimism is actually FATALISM!

#11 Oh, Blake!
Somebody please tell him, poetry is immortal, literally, poets are not!

#10 Aww!
You'll score it champ, that day is surely not TODAY!

#9 HAHA!
This funny kind of optimism!

#8 This kind of signboard!
Yes, yes, you'll make it, TO THE HOLY WATER!

#7 Do NOT underestimate!
But hey, don't over-estimate! Fishes can't fly! Accept it!

#6 LOL!
If only he could've refrained himself from adding the last line of the tweet!

#5 This is height!
Optimism reached to newer heights of insanity! The board should've also mentioned about the season of this waterfront, though!

#4 Waiting Waiting!
Waiting involves a lot of hope! If only people could've understood this, life of an optimist would have been much more simpler :P

#3 Honest answers!
This sign board is so full of honest replies from a completely optimist patient.

#2 DADADADA
LOL, the best advertising ever seen!

#1 SOMEWHERE!
But somewhere there will be night too! Switching off the light n dozing off seems a better option to me, but I am not an optimist!
