See the weird omission of reference to self? Here's something I didn't originally intend to share... The reason I notice this is because I used to type emails like that. I don't know why I used to do that, but I eventually stopped doing it consciously because I thought it sounded weird, and years later noticed it in the situation I mentioned earlier. I find it annoying these days to read people doing it. I totally get what you're saying about ESL, but I'm referring to it happening outside of non-native English speakers. I'm interested in your initial suggestion, though. Thanks!

I sometimes omit first-person pronouns and some other words when writing text messages, because I find it considerably more difficult to type there. The charitable interpretation I would give is that, if someone writes emails like this, either they're writing on an inconvenient mobile platform now, or they're used to writing on such a platform and write that way even with a proper keyboard.
