Same/Similar Food Urges

I get food urges when my siblings get them, especially when my brothers get them. I get this experience a lot when it comes to my two younger brothers. For instance, today I bought Sushi Family Pack after running around in the mall for a bit. When I got home, I ate a bit of it. Later in the evening, my younger brother surprised by suddenly visiting us along with his family–I had no idea whatsoever that he was coming. I looked at his face and then I realized why I got this strong urge to eat Sushi today. The fact is that he loves Sushi and he always eats seafood with his family. This is an indication of scent-based telepathy, I think.
