I am in my early 30's, married, and have multiple young children. I have a lot of co-workers in the same age bracket that doesn't have children but are on the path (newly married, or engaged, kids in the future in the next 5-10 years).
Often topics of discourse in the office revolve around childless couple talk like:
- Taking vacations to romantic/dangerous locations
- Annoying kids in supermarkets
- Annoying kids in restaurants
- Annoying Breastfeeding at the supermarket (see below)
- Having hobbies
- Reading books for pleasure
- Friday night parties
- Saturday night parties
When they ask if I am going out on the town on the weekend, my response is usually: no, I have children. They get annoyed and say that is what babysitting is for. Any other married w/ children friends get this. We can't afford, or feel comfortable, in using babysitting services on a weekly/daily basis for our children. We generally save those things for emergencies (which happen constantly with a family with young children, like babysitting so we can go to work and earn money).
Basically, how can I tell non-parents they just don't understand, and when they are a parent they will get it.
Breastfeeding update
Often when my wife breastfeeds in public we hear audible sighs, groans, side snickers, or laughs. This occurs often enough to be comical. As for the purpose of this question, we have seen/heard these occur from childless couples in the above age groups that odds are will have, or may have, children in the future. So the above question applies, "wait until you have babies that are hungry and you're at the supermarket".
Note
For the sake of full disclosure, it would seem relevant to state in your answer if you are a parent or not.
