A month ago I organised a date and booked a restaurant for a girls night out with my NCT group. We only get to meet up now a couple of times a year, almost 3 years after meeting. Anyway I've just had an email from one of them to saying she saw a couple of friends from a toddler group she goes to and invited them too. She thought the more the merrier and is that OK? I don't know the two friends and out of the 8 of us only 3 really know these two. AIBU or am I just over sensitive having been stuck inside for over a week with 2 DSs with colds and a stomach bug.
