"Bystanders could really help stop bullying if they stood up right when it is happening!" based on her knowledge, I can infer that she has been bullied because she wants bystanders to step in and help.(she's probably been in a situation where she wanted a bystander to step in and help.)
"Lauren Graham (Lorelai) and Alexis Bledel (Rory) each do an excellent job portraying their roles in this dramatic comedy. They act alongside a fabulous cast of quirky characters who make you envy their small-town life." Based on the text i can infer that the author of this review really enjoys "Gilmore Girls".
"I was never in love with vampires until Twilight came out. I didn’t know it was possible, but Stephenie Meyer changed the stereotypical blood-sucking vampire into a beautiful god-like creature." Based on the text I can infer that "Twilight" changed the authors perspective on vampires.
Based on the photo I can infer that the bus has been abandoned and probably doesn't run. I can make this assumption because the bus looks very old and rustic, it looks like it hasn't moved in a while.
Based upon this photo I can infer that the kitty just had a bath. I know this because the fur looks wet and there's a towel wrapped around it drying it off.
Based upon this photo I can infer that this is a photo shopped picture because no one could stand on a flower like that.
Based upon this video I can infer that the people doing these actions aren't very experienced.
