HELP WITH FACEBOOK PLEASE?

[IamRisKinG]

Hey guys I have a friend and we message each other a lot. I was wondering if there is an app or a way to find the message that he sent me with his location services on so then I will be able to tell where he is. This is very important. I can't ask him personally bec yeah lol I'm planning on surprising him with something. We sent each other about 12 thousand and I don't really want to click through each message of his to see which message had location services on so I can tell his location but I will if I have to but I'm putting it off I need to know before the end of the week... So if anyone could please help I will reeeeallly appreciate it.
