What should I say to him?

this really cute guy ive been noticing around my apartment complex just lately has been coming up to me everytime I am out walking my dog, going on and on about how cute my dog is and asking so many questions asbout my dog. I saw him today, and he even remembered my dogs name from when he asked me the other day lol. Well today he told me he was in town for 2 weeks visiting his dad. bummer... he lives 3 hours away from me. well, we told eachother wed see eachother around. Well, he is always outside. What are some things I coud do/say to capture his interest? I just think hes gorgeous... but darn not much time. lol
