and at the end of the day, you just want to go home and have her there waiting for you.
sleeping in your bed because it's too late and she fell asleep but with a note on your pillow saying "don't forget of my goodnight kiss, even if i'm already sleeping".
and so you kiss her gently, you don't want to wake her up. and she doesn't wake up.
you lie down next to her and fall asleep. when you wake up, you realize that last night she wasn't waiting for you, there was no note on your pillow, you didn't give any goodnight kiss and you lied down next to no one.
and at the end of the day, once again, you return home to no one.
