Social Anxiety only in certain instances?

[Hutchie09]

I have never thought of myself as having social anxieties until one day I thought about the fact that I have such a hard time making eye contact when I'm walking toward someone. I will avert my eyes everywhere but the person I am walking toward...to me it just seems awkward because you can't really engage them in a conversation as you're passing by...so making eye contact just seems awkward to me...there have been a couple of instances where I will say hello to the passerby and in those instances I have been received warmly with a cheerful hello in reply....but for those 20 seconds or so when you're close enough to the person to tell where their eyes are looking until you pass by them just seems like an eternity to me...I used to have a problem making eye contact when conversing with someone too...but I forced myself to think "Who cares" and I did it and I'm pretty good at it now...I just don't know how to alleviate these tensions I get when walking toward someone.
