I took a selfie on Instagram now I'm scared?

Shock horror! A girl liked a picture of a girl!? That clearly means she fancies you.
Seriously? You're freaking out over a like on a private profile (which I presume only friends/people you accept) can see? I'd be more freaked out if a random person commented on it saying "alright hot stuff..what's your number " - that is creepy.
Pressing the like button means nothing. Maybe she thought it was a pretty shot of you. Maybe she thought is was a clever shot. I liked a picture of my friends cat..so what? I liked it, and haven't looked at the picture since. Doesn't mean a thing

*and judging by a previous question about flashing on skype (unless there is another meaning for flashing?) - you flashed someone on skype and are worried about someone liking a picture. I'd be more worried about the person on skype saving that image of me to use against me at their will (it happens)
