I know how you feel, but there's no need to go on and on about it.
我知道你的感受,可是也没必要这样没完没了。
Remember me to your grandfather please.
请替我问候你的祖父。
So, celebrate your success, and invite your parents to celebrate with you, however hard it may be for them. If you continue to be excited about your future, you may come to educate your parents in the same way.
