I'll bet if you'd been around them from infancy you wouldn't be

an early age--even prenatally--confers immunity.

According to an allergist I used to see, it works both ways. You can develop an
allergy by excessive exposure to the allergen. In fact, he's absolutely certain
that I will have to get rid of my cats sooner or later.

And it is true that I developed an extreme allergy to dogs by keeping Scottish
terriers in the house for a couple decades.

I think your statement applies more to plants than other items. I grew up in the
South and have no allergies to any plant common in the area. I'm allergic to a
few that are common up here, though.
