How do you know if a girl likes you in middle school?

It's simple really.ok if the girl says she likes u really loud or just loud enough so u an hear then thats a good sign.if she looks at u alot then thats good also.if she walks faster whenever both of u r walking down the hall then thats good 2.if she talks to u alot and flirts with u or if she never talks to u thats really good.
In middle you can tell if a girl likes you easily. The girl will usually talk to you, smile, tell you she likes you, tell her friends she likes you or write you letters.
