Morning Laugh

I wore open toe shoes this morning and my co-worker (an older woman) told me that it wasn't time to wear open toe shoes (although she's wearing sling backs) because it's not summer yet! She said that she wouldn't start wearing open toe shoes until May or June. So my opinion is that if it's warm enough to wear them, who says I have to wait until it's officially summer? Also, if you can wear sling backs (with the back of your feet out) why can't you wear open toe shoes or sandals (with the front of your feet out)? We had a whole discussion around this issue and funny enough, it wasn't our first! What is your opinion?
