I cant spell to SAVE myself

The twins and I were at school the other day and the kids had to draw a picture and the parents had to write a story under it using the words the kids told us.......

well what my kids wanted me to write and what I knew how to spell was very different......

I felt so bad! (knowing that they didnt know what I was writing but the fact that one day they will know)

What can I do I dont want them to think I am dumb? but I have tried really hard and dont know how I can improve myself..... But I feel dumb?
