What is wrong with "The boy starts getting tired"?

[podgorsk]

The same question here. It should be accepted.

[BalvinderC1]

Ditto.

[DBlomgren2]

I wrote the "The boy is starting to tire."
For me "to tire" is exactly the same as "get tired." I think my answer should be accepted as well.

also what is wrong with "the boy is getting tired"

[BalvinderC1]

I think this would translate as 'Pojken blir trött', i.e. no separate notion of 'starting'.
