pkpk was crying last night and now her eyes are swelled up.  Tears are strange; you cry when you're happy and when you're sad.  This discussion of tears reveals a terrifying plot!
Yeah, I don't know if I've 
ever seen kr-chan cry.
Es cierto, creo que no he visto llorar a Koro-chan.
Ahora que lo dices... creo que nunca he visto llorar a Koro-chan.
Sim, acho que nunca
 vi a Krzinha chorando.
