Okay, I thank the Lord for answering my prayer (I prayed about the whole GIRO fiasco) and turning the bad into the good. And guess what? My pastor was right.
God DID turn the bad into better. Ms. Aishah is going to give me a new copy to get the correct parent to sign on Friday, and my dad (who is the account holder) is coming for the talk, so I don't even need to hand it to her the following week! He can just sign it on that day and return it to her! Easy Peasy! I am going to graduate from Primary School!
It's even better than before. The key to it all was faith. I told Him in my prayer before I went to sleep that 'I put my trust in You, Lord, I give You my faith and my trust' and I did. And he heard me (He always does) and turned it into something better, even better than before.
