I knew there’d be some responses about people being ill or in pain etc. Not everybody is ill or in pain on holiday. Couples not talking or even looking at each other at mealtimes, makes me sad. Ps I’m on my i pad , browsing mumsnet, reading , having a nice time
You are seriously spending a holiday abroad pissing around on your ipad/the internet, posting on mumsnet and moaning about people not being friendly enough with you.? 
That is beyond sad and pathetic.

I think there is a reason people are not very keen to fall into conversation with strangers on holiday: everyone has had the experience at some point where you have a 10 minute polite chat with someone at the bar or on the beach, only to find that they seek you out the next day and the day after that and before you know it, they are expecting to spend time with you every day and exchange contact details at the end of the holiday to meet up again. Just one experience like this is enough to make you learn your lesson and be more reserved, hiding behind your sunglasses.
THIS ^ A few years ago, we went on holiday to Spain, and DH decided it would be a good idea to chat non-stop on the coach to 2 (British) women on holiday together - around 10-15 years older than us. For the entire week, these 2 bloody women bugged us, sitting at our table at breakfast, sitting next to us at the pool, sitting next to us at the fucking bar!
I tried to ignore them after a couple of days, but DH kept gasbagging to them. Got to the point where I started walking off and going off on my own with the kids, and the one woman said (as I walked off) 'have you two had a row LOL?'
Stupid cunt. 
Ruined my holiday it did. I partly blamed DH too, as he kept fucking yacking to them. I wanted a holiday with my husband and kids, not some random fuckers I don't even know who latched onto us.
The OP sounds exactly like one of these women. Very annoying, intrusive,, 'why won't you LOVE me?!' kind of irritants!
As someone said upthread, if you think everyone has a problem and is being funny with you/miserable.anti-social, then you have to question if it's you. In the case of the OP, I believe it is.
