We've been meeting more parents out and about and most have been lovely. A few though I've felt like are kind of aggressive when we've been chatting and want to get in a pissing contest about everything from our LO to ourselves. I usually end up putting myself down or lying about milestones (not in the good direction) so as not to give the impression of competing but I feel like there's probably a better way of tackling this problem.

Any masters of conversation that know how to undue the pissing without offending, lying or just walking away?
