hard to say who was more embarrassed during this exchange

So on my last excursion in Barcelona my friend and I went for a stroll up Las Ramblas which is 1.2km long street bordered by the Gothic area on one side and the Raval area on the other. On the boulevard all the way along are kiosks selling whatever you can imagine, from flowers to magazines to bunnies and chicks. Tons of buskers too. I had been drinking wine on Friday night, as you do, and was in considerable pain on Saturday. As much as I love wine, and there is a whole lot of love there - I mean c'mon I live in France - it is not worth it because of the inescapable heartburn that accompanies it. Burn baby burn, sometimes I cave though and give into the consequences. Anyway, before I could tuck into my beer I had to go the pharmacy to get some heartburn stuff. The nice lady, who didn't speak a lick of English (if you can imagine i did charades to convey my message), sorted me out with some strong stuff and I took it to the counter to pay. Get to the till, and the nice lady there said to me "no can sell.". Points to my stomach and says "YOU HAVE BABY?" .

gave birth the next day to a one year old.

then there was a huge awkward silence after I said "no, i have lunch". Just enough time to break a nervous sweat and then I ran away (as you do when total strangers think you are pregnant and the last time you had sex was so long ago that any baby you could have had, would be toddler age by now)
