I feel so bad. Please help

I live very close to the school, it's about 10 meters away. So yesterday about 9-10 pm me and my friend's did something really bad. We threw egg's at the shool. So today my teacher found it out and saw the plashed egg's at the school. He knew it was me (Don't ask how). He was very mad at me and he contacted my dad about it. What should i say to my dad !?!? Please help! I would really love any suggestions what to say to my dad so he won't get mad. Should i lie? Should i blame someone else? Or should i tell him the truth?

Hi tell him the truth..... and do not worry...... I did worse myself in my day!!! Just say you are sorry, and you will not do it again. It will be all forgotten in a few days.

Tell him the truth and apologize. Don't worry, when you are a few years older you will all look back and laugh at this incident. As kids we all do such things...they are not bad....they are mischiefs.
