I have a great relationship with my in-laws. So very blessed by that! I call them Mr. Howard and Mrs. Debbie, but my FIL told me the other day to call him "dad". He's always wanted a daughter (because all they had were 2 sons) and was excited that his son married me. My husband's brother will 99.9% never get married or be in a good relationship. Basically, I'm the only "daughter" my FIL will have. I'm not sure what to do. I think of my in-laws as my second set of parents, but to call someone else "dad" is weird for me. If I called him something else like "Pop", it wouldn't be so weird. I just don't want to hurt my FIL's feelings if I tell him I can't call him dad. 

Because I've found the names "Grandma" and "Grandpa" to be the miracle cure for this little discomfort....


After awhile it grows on you.
