Punctuate the following using capital letters wherever necessary:
my brother said to me you should not waste your time on sundays
'My' begins the sentence and hence we must use a capital 'M'.
'My brother said to me' indicates that the given sentence is written in the direct speech. Hence, we must put a comma after 'said to me'.
The rest of the sentence must be written in the double inverted commas and it should end with a full stop as it is a simple sentence.
Also, 'Sundays' should begin with a capital 'S' as it is the name of a day.
Answer: My brother said to me, "You should not waste your time on Sundays."
