Three trees make an equilateral triangle ABC. There are three mice a,b,c. They began to move simultaneously at the same speed, a from A to B, b from B to C, c from C to A, not necessarily via straight routes. Each one moved closer to its individual target by each step. And eventually everyone reached its target at same time. During the process, a and b met twice, b and c met twice, c and a met twice. Is it possible?
