It doesn't necessarily mean anything.
they act active make funsounds and jump around
It seems like it has to do with something but it really doesn't.
u stop smiling at him
I think it would be a hyena. Dogs also smile :) but I'm not sure if they do all the time. I think its hyena because it seems that they always have there mouth open, and when they do it looks like they're smiling :).
no... it's just their make up that made them look like smiling....
It just depends on what u talkin about
yes and no for one he could just be smiling at you then again he might like what he sees and just letting you know it by smiling at you nothings wrong with that if you aren't interested him ignore him pretend like he's not even their eventually he stop looking when he knows your not concerned that he's looking
Since I am a girl, you might want to have an answer from their point of view. It usually depends on how well you know them. They either are just happy and smiling, they like you or they just heard a joke and was recently laughing.
pretty much just talk to him and flirt a little by smiling at him or by winking
That she likes u alot and want's u to ask her out :)
no Maybe, if you like her just ask her out.
she probably likes you if she is flirting and if she smiles (smiling is always a dead give away) then you bet she likes you!
