Harry and Ginny let Luna plan their wedding. During the ceremony, Harry looked out and saw a whole section of seats in the front row, apparently reserved for no one, along with now single owl perch. 

After the ceremony Harry asked Luna who was meant to sit there. 

"Oh, they did sit there, in a spiritual way I suppose". She pointed to the seats one by one and said "Those two are for your mom and dad. That one is for Sirius. Those two are for Professor Lupin and Tonks. That one is for Dumbledore. That one is for Mad-eye Moody, that one is for Fred. That one is for Snape and that one is for Dobby. And lastly, the owl perch is for Hedwig, because I know how much she meant to you. I hope they enjoyed the wedding."

She waved into a seemingly empty space, before out in the crowd.

As Harry stood there he felt a tear roll down his cheek. He had never felt so touched before.

I'm crying now.
