Treated my cat for fleas. What now?

I am not sure my cat has fleas, but my friend brought her dog over, & did not tell me that it had fleas a few weeks before! I just but Frontline on my cat (vet recommended, & was the only thing over the counter), but what do I do about my house? I can't find any signs of fleas, (other than white specks) but I'm terrified that it is fleas! Any suggestions on how to clean? Should I buy some flea spray?

Thanks!

How to get to know a guy who works at Barnes and Noble?

There's this super cute guy who works at B&n. He's not very outgoing but he's very nice to me and polite.

I really like him and I'm getting the vibe he likes me back. He always stares at me, smiles at me, asks me if I need help.

I want to get to know him but how? Sometimes I sit in the cafe but that's so limited. I font actually get to talk to him and I can only buy so many books…

There's this super cute guy that works at Barnes and Noble. How do I get to know him more?

I think he knows I like him and I'm staring to get the vibe that he like me back.

I actually work there once a week. But hardly ever work with him. But the few times I have he's been so sweet to me.

He's not the super outgoing type but when he sees me at work his face lights up and he says hi, remembers my name.

He stares and smiles at me a lot. Offers to help me with things a lot.

I wanna get to know him more but how can I if I hardly work with him? And he's not really on social networks.
