Forced Socialization

I think going to dog parks forces you to socialize. Once your dog starts rough-housing and playing with another dog, you're basically stuck in a situation of talking with that dog's owner. You end up knowing and remembering the dog's names before their owner's, which I find weird. My experience has been semi-positive. I guess it does not matter about my experience because it really is all about Samson, but it has been quite odd.
I met a guy there, which I find weird, just because it almost felt like forced socialization due to his dog and my dog playing. He has an Australian Shepherd too named Foster. Samson and Foster bonded quickly so I made my way over to watch Samson and ended up meeting Foster's owner. His name is Sean, or I guess it could be spelled "Shawn." We met about a week ago, and for the first time talking with someone at a dog park didn't feel awkward.
He's not my type at all, although many of my friends would argue that I do not have a type. He's tall, white, very muscular (on the gym robot, meat head side), never went to college, and he's a former marine turned fire fighter. I would say he's not my typical type just because most of the men that I have been recently into (or still in love with) don't come in the prettiest of packages, not that the men I date aren't attractive, its just that they don't normally fit into the generic good looks categories. They typically have a scratch or two to them that in spite of their otherwise attractive features, makes them even more irresistible. Sean on the other hand fits the usual "good-looking" guy... kinda like the type of guy who wouldn't normally be into me.
Again, I met him about a week ago, and instantly got along well with him. We engaged in small talk, kinda flirted, and got to know each other a little bit. At the end of the first day, we parted ways without exchanging any contact information or a last name. That was on a Thursday.
The following Tuesday comes along, and I decide to take Samson to the dog park again. I love to see Samson having a good time, seeing as he barely gets out when we're stuck at home. Thirty minutes pass at the dog park, with barely any dogs showing up, and suddenly out runs Foster. I soon turn to my left to see Sean standing there. Needless to say, I was very surprised because we obviously hadn't made any plans the previous day to meet up again at the dog park. So for the next hour or so we talk, laugh, joke, and interact with each other on a very friendly level. I can't confirm he was flirting with me just because I still think (due to his looks and profession) he's out of my league. Later, we decide to gather our dogs and wash them together at the bathing area. He shares his shampoo with me as I lend him an extra towel and continue on in conversation. As we are leaving, he asks me for my number so that we can arrange another day at the dog park.
See, this may be considered a more than a dog park day kind of exchange, but I'm not so sure of that. We met up again today at the dog park, and nothing really progressed following today's adventures. Aside from picking up poop, talking, and playing with our dogs, no further flirtation occurred. He joked that he might visit me on my double tomorrow, planned to possibly meet up Monday, but that really was it.
Eh... so I don't know. I still am utterly bogged down with the thought of Ern, but that is continually proving to be a disappointment on my end. I don't think he understands.
Again on the subject of dog park socialization, its just weird yet fun, meeting all these people.
