Your story brought tears to my eyes. They are very fortunate to have a caring grandmother and a new friend. I also believe God has a reason for everything. I am sure you made their day and they will never forget that. I smile to myself because we hear so much bad in todays world and it's nice to hear people reaching out to one another.
I think a visit from Baby Blessing would really touch them. Children always love animals around. I will be sure to keep them in my prayers.
