I am very thankful we all get along so well given the proximity of our homes. In fact, I can sometimes go weeks without talking to or seeing my in-laws due to our lives & the busy-ness of it all.
But I'm very thankful we made the decision to move here while our children were still young rather than retire here (which was our original plan). My boys are getting to grow up very close to not only their grandparents but also their great-grandfather. They all have a great relationship with them. I know that we are truly blessed in our living situation.
While it may be unique it really is a blessing for all of us. I'm very thankful I have great in-laws who have made it easy for this all to work. I'm thankful with the time & energy they put in to their grandchildren. I'm thankful for their great-grandfather who just thoroughly enjoys having them around.
