For the life of me I cannot FATHOM why people need signatures on there phones. It's gratuitous and highly annoying when the signature is like five sentences longer than what they actually sent. That's so dumb
A pretty good one would be .:((:rEsPeCtThEoNiOnSftw:)):.
I honestly can't stand them. In my opinion, they just try to make あなた look cooler, and that is the biggest annoyance to me. Just leave the message. Whoever you're sending it to already knows you. Why add something else that makes no difference to the message itself?
