Stunned patients with nurses' reasons for early injection

Teo was seriously ill, so he was hospitalized for nearly half a month for treatment. One day Teo was sleeping, the nurse pushed the door, holding the needle and rushing towards his bed.

Teo panicked and asked:

- What are you going to do?

The nurse smiled freshly:

- Nothing serious, it's just time to give you a shot.

Teo breathed out, but suddenly thought of something green and asked:

- But it's not normal to inject it until 7:00 pm, it's only 5 o'clock now!

The nurse scratched her head:

- Yes, it is true that it is 7 o'clock until the time of injection, but today I want to inject it early so that the bacteria will be surprised and unable to prevent it!
