Can you help me rephrase first part of the song "Parents just don't understand",please? Thank you very, very much in advance

1) Parents just don't understand that children are going to make mistakes.
2) The song says that once a mother took his child (the singer?) school shopping with his brother and his little sister.
2) They headed to the centre of town to a large shopping mall.
3) At first, his mother started bugging with clothes she chose (how can I rephrase it?)
4) The singer (?) didn't say anything. He just turned up his nose.
5) She wanted to buy him a shirt which cost only 20$. He replied he didn't like it because it was plaid with a butterfly collar.
6) Then she did the ultimate (how can I rephrase it?) when he asked her for Adidad and she bought him Zipps. He wanted her to put back the clothes because they (?) were going to ruin his reputation (??).
7) His mother replied he was going to school to learn and not for a fashion show. (?)

2. A mother took HIS child? Confusing at best. Is this the grandmother with a son's child?

3. started "pushing" clothes she chose?

6. it was the "last straw?"

This is a song? What song? If I could see the song, I'd know better what you are trying to say.

1) The concept that parents struggle to understand is that children are bound to make mistakes.

2) According to the lyrics, there was an incident where a mother took her child (presumably the singer) along with their sibling on a school shopping trip.
2) They made their way to the city center, to a large shopping mall.
3) Initially, his mother began to bother him about the clothes she picked out (how can I rephrase it?).
4) Instead of responding, the singer simply displayed distaste.
5) His mother wanted to purchase a $20 shirt for him, but he rejected it because it had a plaid pattern and a butterfly collar.
6) Then, she committed the ultimate act (how can I rephrase it?) by buying him Zipps when he requested Adidad. He wished for her to return the clothes since they (the clothes) would potentially damage his reputation (??).
7) In response to his complaint, his mother reminded him that he attended school to learn, not to participate in a fashion show. (?)
