Wonderful week, slightly spoilt !!!!

Just had the most wonderful week at our favourite cl the weather as you must all agree has been something else.One thing spoilt it one family mum, grandad and son lovely grandad charming polite child Mum ?? well we tried good morning, hello, even just a smile but nothing worked she would not evem make eye contact.OH got a bit annoyed, i got upset. should we just have ignored this person, can"t like everybody but it did spoil our break a little, or are we being too sensative.What would you do.(by the way she wasn"t shy she spoke to other people.
