The discrete chemo-taker

Ugh. We went out to dinner last night at the house of some people we don't know terribly well - people from the Other Half's church. And there were 2 other couples there who we didn't really know. Which led to some rather stilted conversation although they were all very nice. I'm just really hopeless with people I don't really know - I can manage a few, but 6 is too many and I just end up clamming up. I'm really just shy at heart.

So, dinner was fascinating - all veggie and dairy-free. We had carrot and ginger soup, then home-made lemon sorbet, then roast pumpkin with a green veggie melange with red pepper and a sort of curried lentil filling plus cauliflower and finishing up with pear gingerbread. I'm still waiting to see how my stomach is going to react to all those veggie - it's been misbehaving on and off recently - usually at 3am - nice (not).

So we got to the end of dinner and I had to take my Xeloda (within 30mins of eating) and I debated excusing myself and taking them in the bathroom, but then I realised that I wouldn't have a glass to put water in to take them so I had to take them at the dinner table - plus I had to ask for a glass that wasn't a wine glass (I wasn't drinking alcohol anyway). Which I did and I tried to be subtle about it but obviously taking 6 tablets with an ocean's-worth of water is a bit hard to do discretely....
So, the chap next to me says 'those look like my pills' and I said 'I don't they will be' (thinking 'I don't think so! Shut up') and he went 'statins' and I said 'um, no, um, these are chemotherapy tablets' which shut him up for a minute and then he went 'they look just like mine' and I made some ha-ha comment about the terrible colours they make these medications, blah, blah. All the while feeling awful. I didn't want to tell this guy, or anyone about them; although our hosts and one of the other couples will know about my cancer from the church - I just couldn't think what to say (other than 'mind your own beeswax!'.) I'm a terrible liar in these situations and I didn't want to not answer because then they might be thinking who-knows-what....
(Dear Other Half suggested afterwards that I should have said they were hormone pills because of my sex-change operation - funny, but I think *not*)

What would you have said? What would you have done? How do you not say 'I have metastatic breast cancer in my bones and lung and I have to take chemotherapy in order to try not to die any time soon...' (No, I didn't actually say that; but I bet that's where his thoughts took him.)

Urgle. Hate.
