1) I have learned about "too ~ to" construction.
"He is too young to travel alone"
This sentence means that he cannot travel alone.
2) Then, what's the meaning of this sentence?
He didn't appear too thrilled to get the car.
Did he get the car? or not?
or Though he got the car, he wasn't very excited?
3) If the "too ~ to" of the second sentence is different from that of the first sentence, why is it? Why does the rule not apply to the second one?
