I sent a lot of short messages to a good friend of the opposite sex on my mobile phone during the summer vacation. How to lie to my mother now?

Hello! You can't hide such a thing. Tell her the truth, you won't believe it. What can you do if you don't believe her? After all, you are her son. You know your son better than your father, and your parents know you best. You have no other choice, and neither does your mother. As a dutiful son, you must pay attention to your attitude, be sincere and not impatient, and finally show your determination to comfort her, and she will be happy.
