MHY
I use both pronunciations. The way I pronounce is depending on how I am using the word. If I am talking about food I would usually say a heimish (haymish) bakery or the food tastes heimish…But if I am talking about a person its almost always heimish (high-mish). Although sometimes I would say don’t make yourself heimish overhere…in the haymish accent. Not sure if this is something others do or not but I do this lol.
