Does anyone else save their work almost after every change that when you switch to a web browser you hit Ctrl + S to save? XP

At one of my former jobs, we devs had to do all sorts of non-dev work, such as writing quotes and even contracts!

The CEO of that company had this naughty habit to contact devs directly without delegating through the CIO. Sure, if it's really urgent like when some system is down because of a bug, go ahead and disturb a dev. But interrupting coders to write some freaking quote? Come on!...

Once, that CEO asked me to stop everything I was doing to write a quote to a customer ASAP, as this was really urgent.

I spent several hours writing that quote. It had to be done right as any specifications in our quotes were used in our agreeements and were referred to in the case of any dispute. So not only were we devs and salesmen in the same time; we also needed to be lawyers.

When I was done and delivered the quote to the CEO, he told me he had no intention to take on that customer in the first place. Instead, he wrote a polite we-are-not-interested e-mail to the customer and cc:d it to me just so that I could read for myself how very sleek a businessman he was.

Me: why did I have to write that quote when you knew all along that you were not going to use it anyway?
Him: It's for your own personal development.

Another naughty habit of that same CEO is that he made "jokes" and remarks that I found inappropriate, such as "You walk like a drunken sailor".

Later, he decided to discontinue our team/product because "it isn't proftable". Well, what do you expect when devs are forced to waste half day completing pointless tasks?!

It was for the better anyway, and I was actually relieved when I left the company. I'm still thinking though, that the real reason he sacked me is that I am too honest and not the docile kind of employee that would be ideal for him. I did question some of my tasks, and worst of all: I didn't laugh at his stupid jokes.

Soooo
I'm a fresh out-of-college CS grad (in his early twenties) working at a small scale startup and the people in my Engineering team are at least 10 years elder to me. (this is my first job out of school -- ignoring the internships and such)
I have a tough time making friends with them and an even tougher time making conversation which I think is hurting my communication skills in a harmful way.
Don't get me wrong.. because they are so highly experienced engineers, I get to learn a lot more a lot faster and I love that part but I just feel like I don't laugh or talk enough at my office (otherwise, people have to tell me to shut up).
I mean when everyone is not plugged in with headphones and cranking the keyboards, they talk about their wives, kids, and stuff that I have no relation to. Like I know a lot about childbirth and car seats but except being shocked etc., I often don't have much to add to the conversation.
Also, on top of this, after looking at the sorry condition of people throughout my undergrad and my internships, I had decided to not get into the habit of drinking coffee. So, when they go on coffee breaks etc. they don't ask me if I want to come along and the times that I kind of forced myself to come along turned out to be kind of awkward and not something I'd wanna experience again.
What do you recommend? Understand that I absolutely love my job and I love learning so much around such intelligent people but I don't have fun at work. Is this Dev life or am I missing something?
Do you have any recommendations or similar stories of how you overcame this problem?
