Hey man
I do not think you're obsessed at all!!
I know EXACTLY how you feel, because my boyfriend treats me the same way......."do you take pictures of anything other than snakes?....... do you talk about anything else?....can you wear other rings besides your snake ones?............why do we have to go to the reptile show...??? ......why did you bring a snake with you?.." , not to mention people at work as well as the neighborhood kids call me "The Snake Lady", and my friends who still work at the pet store are always calling me with questions about snakes because I'm more knowledgeable than ANYONE that works there.
