What a beautiful day here in Tokyo.
Our idiom for today is, "asking for trouble".
This means doing something that will most likely give you problems later on (i.e. Example 1). Or it can mean to behave in a way that is likely to result in problems (i.e. Example 2).
A. I bought my son a new sports car. He looked so happy!
B. You're asking for trouble. He is too young and he doesn't have enough experience driving.
Those kids are asking for trouble when they throw eggs at people's homes.
