I was new and struggled to go positive in pubs.
Tired of feeding on backburner pyro I disconnect from my local hightower pub and open the server browser.
I join barnblitz and decide that I will spam stickies. I had watched a competitive eXtv cast once. I had decided that I would finally abandon my backburner ways and main a good class like demo.

I start on red and make my way to the blu spawn during setup. A medic puts his faith in the baby gibus demoman I was and decides to pocket me. The gates open and I start putting down traps wherever my fov_desired 70 guides me. Our team is doing well and holds of endless waves of waddling soldiers with medics. The medic and I camp in the barn next to a baby engineer with a sentry basically placed on cart tracks.
I'm doing a lot better than expected. Maining demo isn't that bad.
I die and the sentry gun is destroyed during overtime. I look at my score. I'm 42-3. I'm excited. Demoman is amazing!
I PM the friend that got me into TF2 a few weeks before and tell him how much I enjoy the game now (I had transitioned from ps3 Call of Duty that same month. TF2 was my first PC game so I had to learn how to use M+KB. I was struggling until now)
I go to the second point and look at the scoreboard.
Everyone on the server but me has the same ping. Bot. Bot. Bot. It is everywhere.
I look back at the cart. A hatless pyro is standing still next to the cart. Pocketed by a medic standing still. The pyro is trying to put me on fire across the map. I look at my medic. His returning soulless stare takes away every bit of joy that still remained. I sink into my chair.
As I see this my friend replies.
"I'm happy you're enjoying the game!"
"Yea! :)" I reply and go offline

I exit TF2. I did not play for a couple of days. I decided not to main demoman after all.

(Shoutout to Kermit. His comment reminded me)
