history: I am waiting here by the front door. Waiting on the plumber, I hope he will fix my water today! I am sitting by the door waiting on my Plumber to show up. He is late. Oh no_comma_ i bet that is frustrating. Have you ever used him before?
current: He was here two days ago.  I am hoping he can fix the noise in my pipes today!
next: I cant stand noisy pipes. I hope he is able to fix it for you.
