Sea water is sweet

Everybody told me that sea water was salty and I tried to prove it by myself, so I went to where it is and I sadly realized that it wasn´t true, everybody was wrong I thought, for me it was totally sweet,

but yes,

When I came back, I told eveyone that they were right, I told them that sea water was salty, It is disgusting I said. I have no doubt that they are negative people, I have no doubt that they often confuse colors and flavors.
