My little lady who always wanted some decaf coffee. Who always had the right words to say, who would listen when you needed it and who was quick to tell one off all the same. Thank you for your kindness the past year, for your family becoming my extended family too. I love you all.

I met Chlao thru my husband Jim having coffee with Wally at Harding’s in Otsego. Such a fun couple and we enjoyed their friendship with us. Sorry to learn of her death, & was unable to attend her service. At last Wally and Chlao are united in heaven. Good people.
