when someone cries when u cry,when some one gives his shoulder when you haven't walk,some one corrects our mistakes when we do mistakes,stretching their arms without a expectation.some one really makes u to smile ,when you got angry then also he'll smile. He/SHe called true friend.
Someone who knows your flaws, yet still loves you for you. They like the real you. A true friend is someone who would never forget you, and when they are there with you, it doesn't have to be physically standing next to you, because they touch you in your heart just like you do in their's. A true friend wouldn't leave you and follow the crowd. That person who would let you cry on their shoulder, as you would for her/him. A true friend is someone who can make you smile when you feel like you are in the darkest of times.
Here's what you should do: let's call the one you're trying to figure out is a true friend or not Julia, and the second friend will be Emily. Tell Emily to talk fake bad stuff about you behind your back with Julia. If Emily comes running back saying "oh yeah Julia agreed to everything i said" wait until you talk to Julia. If Julia stays quiet, she's not a true friend. If Julia tells you what Emily said, (she was agreeing on everything Emily said so Emily can talk more) she is a true friend. Hope this helped!
