<p>I was asked by a 20 year younger friend how my internet was back then. I needed a moment but then I told her the story of an IRC channel and how we made the day for a young girl who happened to be on our IRC channel. Because this is what my internet was like back then and I wish sometimes it still was like this. Let me tell the story:</p><p>I was 25, the channel members were like 20 to 30 years old. Somehow this young girl found her way to us. She was 14 when she joined the channel. &gt;&gt;</p>
