Explanation:

The grandmother in the story does not mend the tear in the curtains immediately. She first examines it and then decides to mend it.

Reasoning:

1. Examines it: The grandmother notices a tear in the curtains and takes a closer look at it to assess the extent of the damage. This step is important because she needs to understand the size and location of the tear before deciding how to fix it.

2. Mends it: After examining the tear, the grandmother decides to mend it. Mending refers to the act of repairing or sewing a torn fabric to restore its original condition. By choosing to mend the curtains, the grandmother intends to fix the tear so that the curtains can be used again.

Importance of Mending:

1. Prolongs the lifespan of the curtains: By mending the tear, the grandmother ensures that the curtains can continue to be used instead of being discarded. This not only saves money but also reduces waste.

2. Maintains the aesthetic appeal: Curtains play an important role in enhancing the visual appeal of a room. By mending the tear, the grandmother ensures that the curtains remain intact and do not look shabby or damaged.

3. Preserves privacy and blocks light: Curtains serve the purpose of providing privacy and blocking unwanted light from entering a room. Mending the tear ensures that the curtains can continue to function effectively in fulfilling these purposes.

In conclusion, the grandmother in the story examines the tear in the curtains and then decides to mend it. This action is important in maintaining the functionality and aesthetic appeal of the curtains.
