I agree 多一事不如少一事

Why do I feel it's the opposite in this case?

It looked like the kid didn't say enough to explain.

If he was well prepared for the information, he would be fine.

I visited SFO as a Chinese and couldn't tell the officer my classmate's address because she was going to pick up  me at the airport. The officer called my classmate and said she was waiting for me at the airport. No trouble at all.

I still agree with you - 多一事不如少一事
