Aww, he was worried. I didn't log on my game last night because I was playing Harvest Moon. I am going to send him a letter back to tell him not to worry. He is just too cute!!
I have Bones in my City Folk town. He was a starter villager there. Eventually I replaced him with Punchy but then I changed all my villagers back to the starter ones in order to keep playing City Folk as I feel sad when one of my favourite villagers move out which is common in City Folk.
Aww that's really cute, personally Bones is not one of my favourite villagers, but he is so cute and that was so sweet of him to worry, just a cutie! Aww.
