Talking about utility expenses

— I got a bill from the gas company in the mail today. Heating your home with natural gas is so expensive!
— Yes, my bill is expensive too. I guess that's because the weather's turning colder, so I've been turning up the thermostat lately.
— So have I. But I still don't think my bill should be this high. Maybe I should call the
gas company and ask if the rates have gone up.
— Yeah, that's a good idea. I've called them before, and they have good customer phone service. Let me know what you find out.
