Crying is normal... right?!

So, the more I think about this the funnier it seems. I love Skyler and he is a great husband, but he's pretty clueless when it comes to women. :) He finally admitted the other day that he thinks I am the only woman who cries. I'm not offended, I think it's hilarious. It's not like I cry every day of course, but I'm a woman. If I get really mad about something, I usually cry. Obviously the same goes for when something makes me really sad or frustrated. Also, sometimes I randomly cry during movies, commercials, or reruns of Extreme Home Makeover. I thought this was a normal thing to do... but now he's got me thinking that maybe it isn't....??? When we were leaving Chris and Alisa's Saturday night I mentioned this idea to them and Chris said "Alisa cries all the time, especially when she's pregnant. Then it's at least every other day!" And Alisa thought that was understating it! So, in the car on the way home I asked Skyler if he was convinced that I was normal yet and he said "What if it just runs in the family?" So please, my lovely fellow women, can you tell me if I'm normal or are my crying ducts just way overactive?!
