What have you done for someone else wanting nothing in return?

[P-Nut]

Some old lady asked if I could help her open her bonnet as the oil light was on at a petrol station, I helped her with that but also made sure she had enough oil and lets face it a warning light is almost too late. It didn't even register on the dipstick so I helped top that up and get the right grade from that petrol station, it made me late but I didn't mind, she claimed it was done recently so I suggested a trip to a garage for oil leaks.
