Hi,
I live together with a single mother and her daughter. I look after her daughter three evenings a week. The mother likes to watch Dad's Army and thinks it is hilarious to ALWAYS make comments about me being German. Her daughter sings the themesong over and over again and her mum encourages her to do so, especially when my German friends are visiting me. At first I didn't mind but after two years of living with them I just think that this is very disrespectful.
Mother asked me once if I would dislike Jewish people ?! 
Am I being unreasonable?
