I want to be alone

I was in Canberra not so long ago visiting cousins I had not seen in yonks. One cousin suggested I stay at her place next time I came to town (she has a husband and two children). I was polite and thanked her but inwardly, I hyperventilated. The idea of having my own hotel room even though it wasn't cheap was (and still is) my idea of happiness. On holidays, like the rest of my life, I actually need long periods alone. Perhaps there are neurotypicals out there who can also relate. I should add that when I say alone, I don't mean a complete absence of people. I've gone on holidays to big cities like London and Paris by myself and I am quite comfortable walking down busy streets. The lack of a travelling partner is what gives me comfort.
