My friend's son started college this fall. I was his Sunday school teacher in 4th and 5th grades, so we know each other pretty well. He is one of the most hilarious people I've ever met. I can talk to him for hours and laugh the whole time.
When he left for school, I told him that if he ever needed anything to feel free to call or text or facebook. We'd gotten together to talk on facebook a lot before he started to meet people there. Mostly we just joked around, but some of it was serious. He's rather shy, especially around girls, so we talked about how to meet girls a lot too.
He knows I have a keen interest in all things medical, so he asked me (on facebook) one Saturday about a medical question. His stools were black. I ran through the checklist of things it could be. Nothing. I told him to keep me posted. On Sunday they'd turned green. I asked him a lot of questions about what he'd eaten etc. I was pretty sure at this point that it was just something he ate, but I made sure he knew where his insurance card was (he didn't know) and where the hospital was (he didn't know) and I made him promise that he would go in if he experienced any of a long list of symptoms I gave him.
Monday was Labor Day, so I figured he'd be sleeping in. I texted him around noon to see how he was doing. We had rarely texted before, but I was at work, and I don't have a smartphone (I know, right?) so I kept it short and sweet: "Have you pooped today and what colour was it?"
I didn't get a response. I waited and about an hour later he texted back. He was driving a girl(!) to the store and being a responsible adult, he chose not to text and drive. Instead, he had her read the message to him.
He thanked me for that.
