When we were younger, my sister and I used to have a lot of fun on those cascade tricycles. At least, I did. One fine day, she turned around and said that she would not be my rickshaw driver anymore. It was a sad, sad day in my young life. It became worse when she rebelled against all the other things I made her do. Didn't she get the memo that I asked for a sister because I needed someone to do my every bidding? Anyway, it's not as bad as it sounds. I didn't really treat her like a slave (Despite what she might say). Slavery is bad.
If I thought drawing bicycles were hard, tricycles are even worse. I lost interest in drawing that half way through and I wanted to kick myself for thinking of a concept that needed it to be drawn twice!
