We went on a spur of the moment trip to Washington D.C. over Easter weekend to attend The White House Easter Egg Roll event. We, of course, did all the sight-seeing that we could do in 2 days. We visited all the monuments and memorials and when we went through the Franklin Roosevelt Memorial the first time, Liam did not want to participate in picture taking or see the statues up close. So we went through and saw the whole memorial and then we turned around and went back through but this time Liam was excited to participate and lok at all the statues and touch them. The first time through was like a trial run for him to see what it was and the second time through he was comfortable and enjoyed himself.
