“someone just flirted with me!”
“he’s just not into you!”
“i think he likes me”
“i’m so the best”
“i’m a good boy”
“that bitch has got nothing on me”
“he’s dumb enough”
“he’s not worth it.”

HOW CAN YOU TELL?

often people make conclusions, but is there any specific, scientific or logic basis to it?
if not, then i wonder,
do people make conclusions base on their judgements and instincts all the time?
if so, would anything people say be valid?
