She has been a familiar face every day for thirty four years, helping children cross the road to and from school.
Whatever the weather, in blazing sun and pouring rain, howling winds and snow - Theresa Andrews has stood outside Woodingdean Primary School in Brighton with a smile on her face.
But after more than three decades, she has now decided to hang up her stop sign.
She has made such an impact on pupils, both past and present, that they decided not to let her go silently.
This morning a procession of pupils came to use the crossing to say goodbye and wish her well.
Watch: Theresa Andrews
Watch: Children say goodbye
Some of those who turned out this morning were children when they first used the crossing, and have seen their own children and now grandchildren cross the road under Theresa's care.
And that's not all that has has changed. "There were no trees when I started and look at the size of the trunks now!"
Theresa says she is going to miss being a lollipop lady but is looking forward to having some more time to herself in the morning.
And when asked the secret is to being a successful and popular lollipop lady, Theresa has a simple answer: "Being friendly".
