It's OK to not agree,that's how we progress. Everybody can be wrong too,and we shouldn't be afraid to be vulnerable.

Now, how could a satellite service be useless? And what many people don't understand, is that if somebody that is using it (as thousands of people are) hears that, it might be hurtful. It comes down to calling somebody "dumb". And the statement doesn't invite anybody to come up with arguments. No, most people would walk away from a discussion. Avoid this person with his big ideas. This is how society is individualized and how we fail to understand each other.

I also believe that it comes from a good place, like actual "advice". I've been giving my little snarky comment to about 20 people. Most of them were open to it, changed their style a little and the workplace became some much more pleasant.

Maybe you're not aware, but if you notice people pulling away from you in conversation or it's difficult for you to maintain longterm, deep, relationships, it might be partly because of the way you express yourself. And it probably comes from a good place, you might just want to warn people to not go through whatever bad experience you had. But it is a very one way type of communication. It doesn't allow anybody except those that agree. But those that agree won't agree on some other big statement and you'll still resent each other.

Just something to think about as you navigate the challenges of social interactions. The best to you.
