Where's the logic??

I know I've demonstrated some bias ever since I wrote the last post about how I hate my uncle, but seriously, why does my grandma love him more than anyone else on this planet? Because he's the boy of the family? Is that why he gets spoiled?

My grandma had her open heart bypass surgery about a month ago and my mom was normally the one around to take care of her. She took compassionate leave from work so she can work from home and take care of my grandma. A week ago, she left for Barcelona for a vacation with my dad. So she asked my uncle to come take care of her for the week while she's gone.

I normally have school on weekdays so I don't see her that often during the day time, but I know for sure that my uncle is just there sitting in the computer room surfing the internet because my grandma tells me so when I ask.

OK fine. His wife comes over at night time and helps cook dinner for everyone. But a couple days ago, Jeffrey came home sick and got both me and my aunt sick. So she can't come over and cook anymore and I'm still carrying the flu.

Tonight, I helped my grandma cook dinner; Jeffrey was here helping too. And my uncle... well, you've guessed it -- he's sitting in front of the computer. My grandma keeps yelling at my brother saying how he's doing this wrong and doing that wrong. So, I ask her. How come she doesn't ask my uncle to come out and help instead of getting the sick people to cook him dinner? She just answered that she doesn't like his cooking. Well, he doesn't have to cook, he could cut stuff, wash stuff, etc. Instead, she goes and yells at the people who actually help her.

Why is she so ungrateful for the people around her after everything that's happened so far? Are we not worth her appreciation?
