"Welcome home." Then answer with
"I'm home."
I'd be like, they must not have heard me when I already acknowledged that they're home. Let me say it a little louder, "Yes, you're home. Welcome home!" and the ass does it again, "I'm home." LOL Gloves off after that. "Dammit! I just said welcome home so I already KNeW that you're home. That's what "welcome home" means, twit, so Welcome home, damn you!"
"I'm home."
LOL
Japanese authors usually use this to demonstrate how happy a character is to come back home to their loved ones, because if you're single and live alone, there'd no one to say that to you.
One another example is the demonstration of "making miso soup for someone everyday", it might not ring a bell to you, but to japanese readers, it is the declaration of "I want to be with you and take care of you for the rest of our lives".
It's not your culture to do the "welcome home - I'm home" thing, because you're not japanese, and no one force you to do it either, but please do not make fun of other culture.
why not? I'm allowed to make fun of other cultures. Some of them have funny customs. There are some customs I abhor, do not respect, and will never approve of, but on this, it's called humor. That's why the word fun is in there. lighten up a little. No one has bad intentions here unless you thrust it upon them.
Welcome home I'm home is a little ridiculous and rather funny.
I get warm fuzzies when my brother says, "You damn idiot get the hell out" LOL
