Growing like a weed

For several months it seemed like every time we looked at Thomas he was taller, which was mysterious because he eats almost nothing. In fact, convincing him to eat is a daily struggle that almost seems too much for the two of us. Yet, there has been material evidence of Thomas' growth this past year: he has moved from the boy's clothing department into men's (which is more than annoying because his jeans now no longer cost $9.99 but $29.99) and his shoe size went from a men's size 8 to 10 1/2. Finally today we pulled him off his computer long enough to settle the issue once and for all. We pressed him up against his height chart, which we have has since he was a mere wee toddler, and saw this:

No doubt about it, Thomas is 5' 8 1/2" tall and not even 14 years old. What's in store for us?
