Dear Anna,

____ If you have any idea where it might be, please call me.

____ I think I dropped it during the concert so it might still be in the symphony hall.

____ I tried to call you but your mom said you were still at your optometrist appointment (I hope your new glasses look nice!)

____ I really need it because I have a math test tomorrow. It’s crucial that I study for it because it makes up 30% of the final exam.

____ I’m really anxious, because I can’t find my backpack.

Thanks,

Linda
