Some people just don't know how to express themselves.
Some people just don't know how to keep their skin on.
That would be me.

I have been paralyzed by my inability to keep my big mouth shut.
So I have designed a life whereby I can work and socialize but I don't leave the house. You see, when I do leave the house to go for a bike ride invariably my mouth opens and things pop out like, "Get off your cell phone or get off the bike path!!!" I also say kind things occasionally especially to families with children, elderly people, or dogs.

My H has the opposite issue. He wouldn't make a peep even if someone was nailing his thumbs together. So I made him his own personalized emoticons on those days he may want to share his feelings.
Indirectly.
