Seriously, not even joking, talk about the weather. It’s not that most people are really that interested in weather (some people are, but not most), so much as that they’re just trying to start a conversation. Also things to ask: So, what do you do (job)? If you’re younger, what classes are you taking? Oh, yeah, who’s the teacher on that one? Oh, yeah I had him/her – pretty strict with the tardy policy, eh? Or, oh, I don’t know much about them, are they good?
Also, it may feel stupid to you, but it’s almost never that other people will think it’s that stupid. They are just as concerned about talking and not being awkward and not saying stupid things. So while you’re saying “Uh…. I’ve got legs”, she’s thinking “Omg, he’s talking to me. He’s talking to me! He’s talking to me!!! Thank god he’s doing the talking. Omg, what am I going to say next? I have to say things? With words? ‘Um… Yeah, legs are the best! You can totally walk on them and stuff!’ Omg, did I just say that legs are the best out loud? I totally did. I’m such a loser. I’m going to go home, crawl under the covers, and die about a thousand times. Then maybe have some ice cream.” Evidence: Number of times a girl has talked to you and you thought “This girl is so stupid, and clearly a loser, and I should obviously put effort into publicly shaming her”? Number of times other people have thought that of you. Really, everyone goes through this.
