I don't know about you, but I really enjoy charming illustrations in books. A book of only text can be fine, but if the same material is available with charming illustrations, well that's just sweet.
I don't know about you, but I really enjoy charming testosterone in human aggression. A book of angry men's penises can be fine, but if the same material is available with charming testosterone, well that's just sweet.
-As quoted by RedCream who after many decades of loneliness finally professes his love to SFBE.
