I texted you one time, to ask if your sister was home. You said, "Yup." I asked if you could ask her to text me, since I don't have her number. You said, "Sure." I said, "Thanks." That was the entire conversation between us. It felt weird, sending you a text. And your replies made me feel even worse. It was obvious that you didn't care about hearing from me. Besides, I asked you to do one thing, and you did nothing. I got no text from your sister, nor did I get her number. It's nice to know how much you care about me, your friend. And more than that, you couldn't even text back "Hi" or "Hello". If anything, you could've given me an honest answer, but you didn't. I guess I won't be texting you for anything anymore. Bye.
Texting an ex for a reason unrelated to him, and didn't get the answer I need.
