I hope it wasn’t too cold for you last night in your room.
We probably should have a portable heater already, but we don’t. I did order some that will arrive next Thursday. I will check out stores to see if they have any good ones available now. I also called an HVAC person to come look at the home air system. Thanks for your patience. This is a good reminder that it’s better to prevent problems rather than scramble to fix them. An ounce of prevention is worth more than a pound of cure.
