This is the worst situ we had recently.
DD (7yo) invited friend to ours for playdate, 2 days later, DD started nagging me when would she be invited back. DD wanted me to ask the other parent when would she (DD) be invited back.
I explained to DD that
- it was rude for me suggest DD be invited back
- We needed to give them more time to figure out a convenient date
- DD might never get invited back, that's life.
- No matter how politely I might ask about DD being invited back, they might take so much offense that they would never let their child come to ours again.
I tried to playdown the fact that DD has almost never been invited back from any playdate she has hosted. I could not conceive that DD would be invited back on this occasion, either.
DD was having NONE of it. Several times she came out of her class demanding that I accost the other parent immediately (keep in mind playground is crowded, other parent is leaving at speed, and I have 3 other children to keep an eye on at such moments) and ask when DD could come. One occasion she went into huge hysterics about the whole matter (DD is good at hysterics).
Now I have learnt that whenever I agree to let DD invite anyone around, it has to be on the condition that DD must not expect or ask (me) to be invited back. But at the time of the mass hysterics in playground, I finally resorted to a threat -- "I will never invite any of your friends around again if you keep this up!"
That threat didn't work either (not at the time, anyway). But you can perhaps see why I find the whole UP thing completely unhelpful at such moments...
