Heather who?

I'm wondering who this Heather is. Apparently she knows the same people I do and they often look right at me and call me by her name. I have multiple people who know me, and my name, and they will say, "Hello Heather" and "Bye Heather". I thought it was pretty funny when the same person did it multiple times. The most recent when I was getting coco at work. He said his customary ...Hello Heather... poured his coffee and then turned to me with this look of horror on his face and said, "Nicole, sorry..." Yesterday I went to get my nails done. I go every two weeks for a fill. The same ladies have worked at the salon ever since I started going. As I was leaving, one of the ones I chat with often said ....Bye Heather....

Heather, who are you and when are you going to stop following me around?
