I have a weird sense of smell. Most of the time it's not sensitive enough, so I miss out smelling subtle things. It makes me wary about using gas cooker. That being said, sometimes I smell things others do not smell. Dont know why, I just do.
Like every now and then I smell this familiar smell that I associate it with a certain someone in my life and it happens in places that had nothing to do with that person. Like in the middle of this chinese shop in NL. I used to try sniffing around to find the source of that smell, I dont do that any more because I never found it. So, when it happens I just observe it until it's gone.
Today, I just realized that it smells a wee bit like H2O2 + CHNaO3.
