dunno what brings me here.. lols

ppl tend to step into one's life unknowingly & step out of it suddenly..
or shd it be the other way round? depends on situation, i guess..
from the beginning till the end, each steps they took, footprints are left..
there may be some nice shapely footprints (good memories)
& some odd shapes (sad memories)..
there may be a few ppl stepping in & out of it thus making it difficult to find who's whose.. complexities took place then..
can't the footprints disappear?
what will happen if someone new came in?
can they really ignore the prints left?
can they?
