Cover art for Pigs on the Wing (Part 1) lyrics by Pink Floyd

the lyrics are

If you didn't care What happened to me And I didn't care For you We would zig-zag our way through the boredom and pain Occasionally glancing up through the rain Wondering which of the buggars to blame And watching for pigs on the wing

i have no idea wtf it means, but I'll take a stab at it.

People can go through life completely careless and apathetic. If they wanted to do this, the only things they would have to worry about are who to accuse as the source of their problems (buggers to blame), and worrying about threats to their lifestyle(pigs off of their wing, approaching or riding with them during their life)
