I really struggle with people that talk a lot.

There are some colleagues at work who talk and talk and talk and talk.
They're great resources of knowledge but sometimes their knowledge becomes a talk fest. And I end up sat listening. It doesn't feel like I'm apart of the group I feel very excluded.
I occasionally do interject with force but it can be met with silences which then means the talk fest ends.

I'm a very calm and quiet person and even within a group setting I find I have always happily observed listened and added comments at a pace where by that patience is returned.

At work it always feels fast paced/competitive and just overtly showy.

I get that sometimes some people are showy, and there are others that behave this way because they are in fact nervous too.

But I do find it incredibly overwhelming and a little off putting to say the least.
