Input: Ok so today i was at the library with my friend, and her other friend (let’s call her Kate) and it’s the first time i ever meet Kate. 
Everything was cool we made introductions but, they seemed to be stuck on a project that’s due tomorrow and both of their phones are out of credit (in my country there’s this thing called credit, you use it to make calls)
I offered Kate to make a call so she can call another friend and get help for their project, and to be extra nice (i care too much about first impressions) i told her to use my phone, then went back to my desk. Few minutes later she’s gone.. with my phone.
Half an hour later my friend arrived and i asked her where the hell Kate is she told me she left. 
We searched the whole library for my phone then we found it by my friends laptop.. 
Out of frustration that I might’ve lost my phone, i spat “is your friend stupid???” A few times
My friend was taken aback and was just like whoa chill and she was upset, Kate should’ve gave me my phone back in person, or at least put it on MY DESK, which was right in front of her. 
AITA? 

telling my friend that her friend is stupid
