To the gentle[wo]man that stole my front wheel, seatpost, saddle, and collar: next time, just try to take the whole bike. Really, it'd be easier for me to walk home without the un-rideable bike. Also - you stole the collar? Really? No courtesy.
I guess my overall feeling is not violation, because in the back of my mind I always knew this would happen. Now that it actually has happened, I feel that whoever did this is pathetic... Really now, how much of a ****-stain of a life must you have to resort to sealing bikes/bike-parts?
