When mother was younger, we visited her friends.

She took me to the market to buy vegetables.

She took my brother to town.

She taught me the names of plants.

When mother grew older, her back bent.

She stayed home more and talked to our neighbour's children.

She fell sick more often.

She walked with difficulty.

Her grandchildren went to visit her during holiday time.

Neighbours brought her milk from the shop.

When mother was younger,  she was stronger.

Now, mother is older, she is weaker.
