How are people I don't know have my number and texting me?

I have an Iphone 4 and a couple of days ago I got a text that said they were someone from my school. They said Hey this is *persons first and last name here* from *persons grade*. What's up? (:
I have the persons number that they said they were already on my phone with their name labeled and I'm POSITIVE it wasn't her. I know for a fact she would have told me if she changed her number.
And today I got another text from a number I don't know. It said:
Hey!(:
~SINGLE~
I don't know who that is and I'm sort of getting creeped out, especially with the ~single~ label…
Does this happen a lot to anyone else? Because I've had a lot of phones and this has never happened until now and I want it to stop…

Sorry for so long of an explanation… But please help i'm getting annoyed by this

all answers are appreciated.

I want to ask for a Microsoft Surface for Christmas. I'm a tech-savvy person feel drawn to the touch cover component and the fact that you could connect a printer through the USB 2.0 port. I don't really care much about the Windows 8 Pro coming out next January because I don't really need a slightly stronger (technically and visually).
Personally, I'm sick of Apple products because my family has so many of them (iPhones, iMacs, Macbooks) and have not worked with Android tablets.
