yes, yes. i thnk smiling at him when you're at the bar that you went to might do the trick.
but if it still doesn't work, i was thinking that maybe you can write him a letter and tell him, "hello. i'm (your name); a neighbour of yours and was wondering if we could get together sometime whenever you're free". or maybe you could have a party at your house and invite him. just knock on his door and say, "hi. i live just along this road and on such a day at such a time, i'm going to have a party and was wondering if you'd like to come and join the fun" and then give a cute smile or do something flirtatious but do it subtlely. think that might do the trick as well.
i know fancying someone can be problematic sometimes, but if you know what to do it won't be such an issue. as for me, i'm still thinking what i should be doing...should i just tell the guy that i fancy him or should i let my friend have him? *shrugs* ugh. i really don't know what to do.
