What Is A Message that An 18 years old boy want to send to a 15 years old girl!~!~!

It is very disappointed and impossible for some body said that an 18 years old boy miss a 15 years old girl. May be it is and may be the answer is not. But I really don’t understand the reason why the meaning of missing is really pity and sad.

Just think deeply, if you give up now, what will happen to me. I will down, you know? I knew I am always lecturing you, asking you to study hard, hard and hard. I knew the huge and malicious pressure that I gave to you is really burdening you so much. But I really hope that you will keep it up, ok? Study let smart and enjoy the process of learning. You are 3 years old younger than me I hope that you will not waste your time and be regret later on.

Thanks god to let me be here and give me a deep and fresh breath to cheer you up, shelter you and take care of you on your way to success. I have done my best and at least I am not giving up yet. Too many times I have told you the same words and the encouragement phase and I really hope that you will remember it. If you failed to remember it, never mind, I will always be there to remind you. I promise!~!
