I think they call it "post-travel blues". You come home to find that life was seemingly on pause, nothing has changed, and stands in stark contrast to the life you just left. It's boring. It's familiar. You fervently sift through pictures in hopes of sustaining those moments and feelings but it's just not the same. You start mentally planning your return trip but also realize that your life now, here, must move forward. Jet lag is not conducive. The sadness deepens.
I'll post more as I come out of this funk and get back on schedule. I really do want to share/document my time in Vietnam. Until then, I feel another nap coming on.
