If you are not open to new things, stay home...

     If you have to have things like they are at home - traveling is not for you.
     The food is different, the climate is not the same... and, on and on.
     If you are in a café in London forget about getting ranch dressing for your salad. They do not serve chop suey in China. But, meat pies in England and Scotland are amazing and in Ireland the lamb stew is wonderful.  In Italy you will have to like tomato; that's a major crop. If you are a wine drinker the chances are not great for you getting a reasonably priced glass in Glasgow.
     But, when in Rome ... you know the rest. The toilet paper is different ( and better ), you likely will not see a wash cloth in France.
     Traveling is an adventure. If you don't like adventures you will be happier staying at home. The rest of us will also be happier because we will not have to hear you complain.
