I'm mad at my friend but i feel bad for being mad. so he was supposed to come over and pick me up at 7:30-8 and his mom had an emergency so he told me that he was going to check on her. its 10 now and i havent heard anything from him til i texted him. i feel like he could have called or sent a text to let me know that he was going to the hospital and we would have to make plans for another day. instead of just having me waiting for hours.
