Get a compass and find your way back again! I bought this way neat compass ring from JeweledAbrosia's lovely etsy shop - I came in the mail today. Its a fun thing to have when lost! Its funny how when you get off the red or blue line (the underground ones) and you are completely confused as to which direction you need to go once you come up to the street - at least, thats always my problem. I think I got this ring for that very reason. No more walking miles in the wrong direction for me!
