I was useless when I first started my job at the nursery. But now I kinda get the gist of ages and milestones. But trying to guess a child's age Is still hard for me.
I am awful with guessing people's ages, like totally awful. I always think older people are younger than they really are, and younger people are older than they really are. I mean, everyone is always flattered and surprised with how old I think they look, which is a perk, but still. So awful.
