I know am not crazy.

 The other day I was at work and I had finish the water I was drinking. So I fill my water bottle up at the sink in my classroom like I have anyway done. When we went outside to play I took a drink of my water and it tasted like bleach. I started gagging. This morning I got water from my tap at home and the same thing happen. I use a different cup too. Has this happen to anyone else. Or am I just crazy.
