Welsh people…is this normal?

I have no problem at all with Welsh folks. A couple of seriously good mates are Welsh. But it is my suspicion that some Welsh people just maybe overdo it? Have you encountered anything like the below, does it embarrass you, or would you defend it?:

1. A mate in London had two Welsh girls to stay for a weekend. He'd met them on holiday. They were quite fit and quite good fun. But they were totally obsessed with Wales. It was almost impossible to stop them from talking about Wales and Welshness. I don't mean their everyday lives in Wales...I mean Welsh history, Welsh culture, Welsh everything...like mini-lectures or lessons for the English, over and over again. Both had lived in Cardiff all of their lives. Every now and then they broke off to talk in what seemed like very broken Welsh with each other...it didn't sound fluent and sounded as if they were struggling...and, hilariously, one of them claimed to have forgotten how to say 'Wednesday' (in English). She was rolling her eyes, giggling, slapping the table and claiming she had forgotten it and could only say the Welsh word. They were transparently not Welsh speakers and it was embarrassing as this seemed highly faked. They were quite nice girls...but they were unable to go for more than about 10 minutes without doing or saying something that absically meant 'I am Welsh'. This is would be very...weird... behaviour for the English if we were off our patch. Is it more normal in Wales?

2. My neighbours went skiing with their son's Welsh in-laws to get to know them a bit better and be mately and familyish. At the ski resort, if the Welsh wife ever overheard that someone else was Welsh, she'd scream about it...shout over to her husband pointing that she'd just heard some fellow Welsh people...and sometimes rush up to the overheard people, introduce herself and invite them to have dinner later or a drink or something, simply because they were Welsh. They often looked a bit intruded on and nervous of her, apparently, although some were delighted. Again...if you were English and did this to other English people, you'd be treated with some wariness and caution.

Views? Do you think Welsh people do/say some rather over-blown things when among non-Welsh people to make a point? Or do you think it's all fair enough?
PS Please don't say it is natural and to be expected :-) It really isn't. I'm keen to find out if the Welsh are embarrassed about this sort of thing, or whether it can be considered fair enough for a small nation to so manically hype itself up when not at home.

can anyone speak simple welsh ?!?!?!?!?

hey guys, i have a welsh oral exam tomorrow, the teacher is going to ask me a set of simple questions about myself and homelessness in wales. i just need simple ways to say these sentences, if any1 can help me say them in welsh i would REALLY appreciate it! 10 points best answer, thanks! x x

homelessness is expected to rise by 12 percent between 1996 and 2016. 50,000 people experience homelessness in wales every year. it is terrible.

i think they are homeless because of lack of jobs and education. wales is much less populated than england.

to be honest cardiff has a largr number of homelessness than abertae but on the other hand places like london have high homeless rates too.

anyone please?? simple sentences don't have to be hard just enough to get the message across of what i said in each part, thanks

A Welsh girl called London, would be stupid?

I'm writing a story and I'm planning to name a Welsh, London.
I don't want to name her like a stereotypical Welsh girl but is London a way too British for a Welsh girl?
