I very much enjoy walking, so much so that I would regularly walk to school even though it would take me half an hour to get there, the monotony broken by the music I would listen to while walking. On the way to school there was an ice cream shop so sometimes I would stop off there and buy a milk shake to drink during my journey. Alas, I have ended up lactose intolerant so can no longer indulge such a luxury. My delight in walking often caused me to leave home on first rising in the morning and walk all day, visiting the whole city, but nevertheless, rather bizarrely, I considered it a waste of time. My feet always started to hurt after 2 or 3 hours of walking.
