Having "Adult Interaction"

So I mentioned this briefly in another thread but I've been meaning to ask about it. I'm a SAHM to 2 small toddlers. Personally, I don't *care* what other mothers choose to do. I've never inquired about "well, why do you WOH"... It's really none of my business nor do I care. I've been in several playgroups for my kiddos and sure enough, I get bombarded with comments from the WHOM about having "adult interaction". I mean seriously...what do they think I do all day?..Do WOHM think us SAHM just baby talk all day and are prisoners to our home and never speak with adults?.. It's funny, b/c a lot of times, they won't directly make that comment to me but will be passive aggressive...saying something like..."Oh I JUST had to go back to work to get the adult interaction"--waiting for me to respond like "oh yes, I agree, I miss the adult interaction"..... Almost like they are justifying why they work! If you are going to a job just to be around adults, that's pretty pathetic IMO. There are a million things I could get involved in that would be around adults, w/o having to go to work. I don't need work to fullfill my adult talk. I don't get it..Why is this always the first comment out of a WOHM? It's an indirect insult or putdown.
