Yes, you can hate her.
A woman from my new mom's class (FTM) labored for only 5 hours, had a home-based water birth, was able to EBF without any issues, plus bank an extra 8 ounces a day for freezer stash, ran a 5K 4 weeks after delivery, fit in her pre-preggers cloths at 5 wks, cloth diapers, makes her own baby food, and had LO STTN at 6 weeks old.
And she was the nicest person on the planet. I hated her for months. Actually, still do, LOL.
