rocks ..... I have collected them since I was a child. My mother.. not so happy about the whole rock thing.... but even what people think are yard rocks, I have to look at them if they have a pattern in them or colors or texture.... well, you get the idea. The postman hates me on the holidays because I order up rocks on the internet for presents to myself.
Things that catch my attention:
Lights .... I catch myself just looking at them sometimes when out in public. Hate it that happens! But always have been that way. In fact, my first baby words were "Light Hot" LOL
