Replying to People assume I snowboard

Mostly everyone in my life knows that I ski (maybe not...) because I talk about winter and skiing all the time and post about it frequently. Yet somehow whenever anyone outside my ski friends talks to me about it, they're like "Yeah so you snowboard right?" And God knows how many times I remind them that I ski they still say... "Oh yeah, that's right! You're a skier." And then the inevitable... "Do you use poles?"..... -.- I'm assuming this is happening to more than just me?
