Biologist and Sociologist in a lab

S: I .. feel like we need to talk..
B: Is everything okay?
S: Yeah.. it's just ... well, you're a biologist and I'm a sociologist.. I feel like I need to see other people.
B: What? .. is there someone else?
S: No one specific, it's just random.
B: Is it me?
S: It's not you.. there's a whole list of reasons
B: (Crying) But, we worked together on so many experiments
S: And that was great.. but I need to move on
B: Fine! But just so you know, I faked all those organisms!

To be honest, just liked the punchline :P But work with it if you please.
