"You have a lot of kids...."

So I have four children and I am young. My husband and I are both 27 years old. We have been married almost 11 years. We get A LOT of comments about those two particular things! "wow you are so young!"😃 "Are they all your kids?" ex. ex. I can go on forever with the crap I have been asked. I however also get a ton of compliments on my children's behavior and try to let those effect me more than the negative stuff I hear. Well today they coexisted. A man and woman happened to be discussing my family at the table behind ours at breakfast. So right away I am on alert and go full mother bear mode.

I overhear the man stating he admired our big family and our well behaved children. So then I am all like yasss thank you! So I am all feeling like I am nailing this parenting thing today.

Then the woman starts to talk.....and I am instantly back to mother bear will maul your damn face off. Her opinion was we obviously did not have any idea how to be responsible. It was a shame our children would never have a chance at anything in life and she just would not shut up! I was red.

I immediately start to discuss with my husband what is going on. but as I attempt to do this I see them getting up from their table to go pay. feeling like my window of opportunity is disintegrating I give her the glare of death. I'm so speechless at this point I couldn't even find words. So they leave and shortly after my husband goes up to pay our check. He is then informed the couple behind us paid our entire tab. I was embarrassed rather than gratful. I hate how I feel about it so I forced my husband to then pay the guests behind us tab so it could be payed forward immediately. My husband said I took it out of context and they meant well. I just feel like his wife completely ruined it as a kind gesture and I feel like it was pity. Am I in the wrong to feel such disdain over this?
