is there something funny?

It happens sometimes where people laugh at me. Not to my face. They try to hide it. Say I'm walking on campus and they are walking towards me, they will have this "wooo" expression in their eyes. They then look at their friend, who also tries to look away and not make it obvious they were staring. I also see a little smirk in their face, which becomes more relax and bigger as smile once they pass me (I slightly look back and see it). You know when you see something that makes you laugh, but you know it's not appropriate to laugh, and you don't want people to see that you're laughing so you try to hold it, but if someone was to watch you right at that moment it would be obvious you're holding something back? I'm sure some of you have done that before or noticed when others doing it, so yeah I can see that too.

It really pisses me off, and I wish I wasn't such an anxious person. I wish I would be able to turn around catch up with them and stand up for myself. Say what's on my mind, make them feel bad with themselves. I would want to say something like: "Is there something funny? Is this funny?" (pointing at my left side). Then I would assume they would feel bad, try to look away and not make eye contact because of how embarrased they feel. I would hope I would be able to continue saying "would you want to look like me?" obvious answer would be "no." I would then want to continue "yeah I couldn't imagine anyone wanting to look like me. But imagine you do look like me. It sucks right? you get up every morning with this face, no girl really looks at you with intrest, but you don't give up you know... you put your cloths on, you try to make something of your life, you go to college, but then two asswhole (should be obvious I'm impying that they are the assholes) are walking towards you, and laughing at you, how would you feel?"

It is pretty tough having your left side of the face paralyzed since you were a kid. You smile, but only one side moves. Every expression you do, only one side moves. Yeah it looks pretty weird. But how can people laugh?! People should be thankful they aren't in my shoes, and be friendly. They shouldn't make my life even more misarble by staring, laughing, elbowing their friend to take a look.
