Not that this is the case here but often people will write something in a chat thinking they are in another game or responding to something happening in another window. You can't draw too many conclusions to anything that happens because of this. Can't tell you how many times I was writing a note about a player only to have it partially get typed into a chat because my turn came up. also, what can happen is I am off getting dinner or a drink of water and am late back to table and a player or two think I am thinking a long time when it has nothing to do with anything in the game. You never know why something is happening at the table so don't try to read too much into it. As others have said, just play your game and assume you're good, you'll know when someone is making a point to you!
