There's a family that rents part of our house. I think I like their son. How do I know if he likes me back? please anybody answer me plzzzzzzzzzzz i want help

Well I'm a guy, so heres what my point of view would be. You should talk to him, realize if you have any thing in common (you probably did that). 

If you have nothing in common, just stop and turn away. 

Don't try, because trust me. When you have nothing in common, then you show your true feelings, you give birth to two awful things. 

Jealousy and Heart ache. So if you guys are probably destined together, just realize, it may not seem like it, but every guy wants a 7/10 girl. 

Please don't take it wrongly with guys judging girls by how they look, but just know this. If you two looked into a mirror, would one stand out? Would one be taller or shorter? Would one be hotter or uglier? 

So yeah, talk to him, get to know him, flirt, keep this going until one day, he would say something. If he doesn't he probably doesn't like you. 

Ooorrrrrr here's an easier way. Just say: "Hey there! I think your very good looking and very nice, so I just wanna say if you like me aswell!" Instant answer. The answers improve if you give it time though.
