I have a friend I met when we were both pregnant and our DCs were born 10 days apart. She works long hours so we don't see each other as often as we could but when we meet we have fun and DCs have fun.
She has an odd way of getting in touch...she always says "Haven't seen you in ages, shall we pop by tomorrow?". That is OKish but overtime she always comes here and we are rarely, if ever, invited to hers. She also comes empty handed during lunch/diner time, so effectively inviting herself over for lunch/dinner.
A couple of times she has been even weirder. She has come with her DC and while they are here, without any prior arrangement, she asks if she can leave her DC with me to go do part of her job (it's out of hours but she does favors for mates, I can't really say more without giving too many details away). So today she came, when we were about to sit down to dinner she said she was not hungry but could we have DC because she has a quick job to do, then was gone for 40 minutes.
That is rude isn't it? She's just using me for childcare isn't she?
