Is it normal to laugh at everything your pet does or whines?

I have a chihuahua named Lady. When she’s sad, she whines in the same tone I say “Awww” in when I find something cute. When she’s confused, she says “Uh?” in the same tone I say “Huh?” in. When she’s annoyed, she whines in the same tone I say “Hmmph” in. When I leave the bedroom light on at night, she covers her eye with her paw to make it easier to sleep. When she’s mad at me, she sticks her tongue out at me. When we play tug of war, she cheats by ceasing to pull and continuing to hold the hush puppy to make me relax so she can snatch it. This only worked once. When I wake her up at night, she snorts in annoyance. One time she was chasing her tail and caught it. She held onto it for a few seconds, then let go. She sometimes licks her privates. One time she attacked me with her breath for waking her up at night.
