I know in most cases unless you have experienced something yourself, it's hard to really know what people go through. Like you feel badly if a friend loses a parent, but you REALLY get it if you lost one yourself. OR if someone has a child with special needs you can only IMAGINE what it is like you can't REALLY feel the full scope of what it is like. I find that people who don't have kids have a hard time understanding what it takes to raise a person/persons. It's like they kind of get it, but they can't fully understand what it is like on just about every level. I am not saying there's anything wrong with that it's just something we as parents have to cope with when you have to deal with people who can't really relate to you. It could be a friend, a sibling, a co-worker anyone! It is just super fucking annoying A LOT of the time, and when you insinuate that that is the case they get mildly offended that you would even think that. Problem is it's true they just can't seem to see that on so many occasions.
I recently made a plan with a childless person, who was taking my child to do something. The plans got crossed over with an important dr. appt. (which would affect the plans that we did make of course), AND although that’s super annoying it is what it is. If we have to understand that you don’t have kids, then please understand that we do have kids!
