Alissa entered the MTC yesterday!  We did the drop off thing and thought it a little bit odd that an elder took her instead of a sister.  
That wasn't what was so hard.  It was the drive home and trying to see the freeway through my tears.  No one could talk.  It was sad to walk into the house and see a few of her things.  We had a few more tears for a few more hours because we felt so empty.  It was such a happy thing to send her off but just so hard to come home and move on.  I have accomplished much more today than I did yesterday.
