I didn't get enough sleep and I'm really tired. But I don't want to go to bed, I want to wake up. So I'm about to get out of the house but sadly, the elevator is under maintenance. Since I live on the 26th of the apartment building, walking down the stairs is kind of a challenge. 1) I can't help but wait for the elevator to work again. 2) I have no choice but to wait for the elevator to work again. If you have something that you want to correct, just please correct them. I have one more question. Which is more natural between 1) and 2)? Thank you so much.
