I love sleep, but can't...

I don't get a good sleep anymore, at least it rarely happens, all thanks to my canine underling. She always barks at the right time of the day, which is whenever she hears anything. Why didn't I spent more time training her not to bark... Well, the other reason could be my aging mattress, it's been around longer than I've been in this country, if only I have the money to replace it *sad fase*.
