Everyone is saying goodbye to someone and hello to someone else.
I'm really not looking forward to goodbyes.
"See you later" sounds like a consolation, so no I don't want that either.
I want hellos everyday.
Hello, I thought about you today and I want to spend time with you soon.
Hello, I'm alive and not about to say goodbye.
Hello, who's this? Oh. I don't know you, I'm sorry.
