My dad used to have a term for my "stealing" other people's rubbish. Manyak, as a verb. Minamanyak mo na naman yung mga paso na basura ng kapitbahay (translating roughly into: You're maniacking the pots that the neighbors threw away). Routinely going through empty lots for salvageable materials is a habit leftover from childhood, when I had half a bookshelf devoted to "garbage".
Of course, it is most fun to steal leaves that people do not want. I use them to compensate for my lack of having a perpetually shedding forest in the yard.
My bike can carry leaves both in the basket and at the back, where a steel contraption kind of holds stuff down.
But I'm also learning how to drive now, in case of emergencies. It will probably be a useless skill once I finish lessons, gas prices being what they are. On a recent short drive home with our pick-up, I loaded the back with alibangbang leaves. Seems the stormy weather makes people scared of falling branches, so there is lots of pruned stuff for me.
