Final batch of Letters- First Round

I will be dropping the last batch of letters at the post office tonight. The last of the first batch that is which is to say I made it through mailing a letter to everyone that I know personally in my address book.  I plan on going back through and writing more personal notes to some people and cards for the kids in my life. I especially like to mail letters/notes/cards/post cards to all the kids I know as I loved mail when I was a child. I have been messaged a couple of times by those who received their letters but as of today I have not received any notes back in the mail.
