Was it an accident?

Am I the only one who hates when people ask you this when announcing you are pregnant??? It makes my skin crawl!! I am 24 married to my husband 7 years we have a 3 year old daughter. My husband has a really great job so really an accident?Our first was not an accident we where 20 years old when we decided to have a baby can it really not be that we are responsible and we actually think things through aggh!?!?  lol I'm ranting!
