Miss you like a dog

I howl in my head before I sleep
Howl so loud, afraid it will be heard
Howling alone into the pillow
Scratching imaginary door to be opened

Miss you like a dog
When you leave it seems like a month
a second after you close the door
When we meet, joyful like a full moon passed

Miss you like a dog
Sniffing for your scent
Closer is better
Closest is best
