In the mood
In Spanish, use the expression estar para followed by a noun or an infinitive to talk about your current mood, patience, or mental capacity for something. It translates roughly to being "in the mood for" or "up for" an activity.
It is extremely common to use this phrase in the negative (no estar para) to express that you have absolutely no patience or energy for something at the moment.
| I am not in the mood to joke today. | No estoy para bromear hoy. |
| I am not in the mood to put up with another complaint. | No estoy para soportar otra queja. |
On the verge
You can also use estar para to indicate that an event is imminent, or that conditions are ripe for something to happen.
This is frequently used to predict the weather by looking at the sky, or to describe situations that are about to reach a breaking point.
| The sky is ready for a downpour. | El cielo está para un aguacero. |
When someone is pushed to their emotional limit, you can use this same structure to say they are about to snap or have a breakdown.
| The boss is so tense that he is about to explode. | El jefe está tan tenso que está para estallar. |
| The boss is about to have a nervous breakdown. | El jefe está para un ataque de nervios. |
