There's this one thing that prevents me from approaching from time to time. I can't tell people's ages at all. I noticed that many people don't really look their age. Some girls look like they're at least late 20's yet they're early 20's. Some girls look like my age but are below 18. If someone looks like she might be a bit old for me, then I don't approach. But then again, there's a huge chance she just looks old... or I'm just terrible at telling people's ages based on their faces. Does this go on other people's minds too?
