Additional expenses for Gabriel's science assignment

Desiree:

I had to get a few more materials for Gabriel's science assignment.  The
additional costs are $15.51 so the total for his project is $40.  I
request that you please submit at least half of that amount at your
earliest opportunity.

Thank you,
Fox


P.S. Please note:  these are in addition to the expenses I had requested
from you on Spet. 8, 2012 which you said on Sept. 9, 2012 you would pay.
