I knew when I went to my current job that I’d probably see people from my last job fairly regularly. This was to be expected since the two locations are separated by a very short city block.
On my way to or from work or during my lunch hour I’ve seen the receptionist, an animator, a designer, a few engineers, and one of the recruiters. In every case, I’ve just smiled, said hi and went on my way. It wasn’t awkward or anything, and really why should it be? I didn’t make my departure into a spectacle (at least I think I didn’t) so there’s still an air of professionalism.
Though it is interesting to note this is the closest geographically any of my two consecutive jobs I’ve ever had. Anyways, I’ve made it past my second week. Yay!
