In full frame terms 35mm is a medium wide lens, not a "normal" lens. For many photographers 35mm has been a favourite focal length for documentary and street photography, because it's wide enough to show context yet intimate enough to show detail. But, it does mean getting close and involved.
It's usually the wrong lens for portraits because it can cause perspective distortion when used up close. Don't use it for a flattering head-and-shoulder. But, it works for environmental portraiture where you show the person in their context.
