Robert Todd Lincoln --The vitals

[L Verge]

That is exactly how I have envisioned him as an adolescent (without doing any real research). I would suspect that his father's long absences while riding the circuit and then his entry into politics would stifle Robert in adolescence. I can also see him somewhat miffed at having to assume an adult male role at home during his father's absences -- and perhaps hearing his mother's complaints about having to run the house on her own. I bet his two, rambunctious little brothers would get on his nerves big time - just as they pester modern big brothers.
