Where do a lesbian and a straight woman have in common?

Here's a jolly funny moment for you:
My dad is coming to visit in a couple of days. I realised I didn't have any winter shoes here so I asked him to pick up appropriate shoeware and bring it to me when he comes to visit. And this is where a straight woman and a lesbian, (where I am a hybrid of both) cross: you can never separate a straight woman from her shoes. However, the fact that it is combat boots with steel toe caps tells you that you're dealing with a lesbian.
Ha, take that, feminists!!
