I can do it all by myself

Today Amy and I visited Anna and her two boys Frank and Eric. Frank used to go to same swimming lessons as Amy , but we had never met Eric. Amy loved playing with both the boys and when we went to the park on scooters, Amy doesn't yet have the stamina for a longer distance, she gave up and decided that carrying the scooted was easier. When I offered to carry it for her she 'wanted to do it all by herself' !!
