Heh, while looking up some stuff, ended up finding out that this strip is based on the AC commercial http://www.youtube.com/watch?v=RimeP3hIDFI. As for the translations, hopefully they're correct.
And it happens to be based on the poem by Misuzu Kaneko as well.
Is that an echo?When I say "I won't play with you anymore"you say "let's go play."When I say "let's go play"When I say "idiot"you say "idiot."No,When I say "I'm sorry,"Anybody.And then,After,you say "you won't play."you say "I'm sorry."Becoming lonely,
