I had a girlfriend who was born without this connective tissue between her brain hemispheres.

Other than being weird, for reasons that could be explained myriad other ways, she was able to control each eye independently when she wanted.

Watching her watch TV and me while I walked past was... odd.

My understanding is that each half of you becomes an independent system. Your right half controlled and perceived by the left brain. And that experiments that hid the left hand from the right, they could prompt both sides to draw something and you’d get two distinct responses.

Idk how that works for a normal life like that

I suppose you adapt, as you don't have an alternative nor a frame of reference of what "normal" is?

Like people born without a limb, or those who discover they're double-jointed or hyper-extensive/-flexible when their classmates react at their ability to touch their thumb to their wrist.

It's definitely curious and worth understanding.
