Hi dulciana
I'm hugely sympathetic, we have a similar problem with ours. My son, very like me, openly externalises, offloading all his worries and woes then skips off happy as a sand boy!
Our daughter lives in France and is utterly impossible to get hold of. She has a French phone contract, cheap as chips, which doesn't allow her to ring or text outside of France. To stop herself answering constant Facebook messages she now carries an antiquated phone that doesn't have email or whatsapp, so the only way we can get hold of her is if she checks her emails in the evening. She is like the Scarlet Pimpernel!
We were visiting her last weekend, arrived home on Monday night. Tuesday night we'd just settled down to watch iPlayer when the phone rang. Young female on the phone weeping, sounded like my daughter, "Oh mum I'm so sorry, I need to come home, I'm so sorry mum, I think I've got aids" !!!!! I was desperately trying to calm her down, telling her I'd jump on a train and get out to her, not to worry etc etc then the phone went dead.
I rang her phone, engaged: we were running round the house trying to find a way to contact her, calling her boyfriend (engaged!). Suddenly the phone rang again, same girl, now calm, apologising for ringing the wrong number! OMG, the girl got such a grilling, I'd decided that it was a hoax call as there was a bit of giggling in the background and she received the mother of all lectures! At the end I said that if she truly had aids I wished her well and advised her to get home to her parents immediately.
We sat down shell shocked with the adrenaline coursing!
