I used to be in a curriculum assembly as soon as the place the speaker requested our group of lecturers, “What’s an important factor you’ll be able to train a toddler?” I began pondering, possibly self-confidence or acceptance … when a colleague of mine, admittedly a complete math nut, referred to as out, “Place worth!”
