Early Bird Special

Throughout my life, I've generally had a bit of a problem with getting places on time. I have been better about this in recent years, but I still make mistakes periodically. In the last couple of months though, as I have had numerous meetings and interviews, I have been playing things safe and have started showing up very early (15-20 minutes) for most of these events. If I'm supposed to meet someone at 11:00 AM, being there at 10:40 AM is sort of rude, right? But standing around outside and taking walks by myself until at least 10:50 AM feels sort of awkward too.
