Context: Anyway , very positive . Such a nice morning that I think I will probably make a habit of walking to the school when I volunteer , and maybe walking to the grocery store and the library , too . Both are close . Heck , I could walk to the dentist and the nail salon and the dry cleaners , too . Though perhaps walking to the dry cleaners with a down comforter and a shower curtain over my shoulder would be a tad awkward .

Question: What may be the reason for them wanting to walk everywhere now ?
