Hiya
No, you aren't being nosey at all!
My family kind of expected it as they could see I was changing - not drinking, no pork and mentioning religion more, so they were really fine with it. My Gran was a little bit but I guess that is just the generation gap and now I just educate her and my family about Islam when I can.
My son is Muslim - he has a Muslim name and has been circumcised. We had an Eid party after his first Ramadan - he was too young to understand what was going on (he was only approx 6 mths old) but we felt that as we celebrate Christmas with the family, they could celebrate Eid with us (you have to make compromises as a revert), so we had a totally alcolol/pork free party and I made some Mid East food for people to try and gave them Eid cards with information about Eid/Ramadan inside the cards and where they could find out information about Islam. It went so well and I'm really happy that it gave people a good impression of Islam and everyone really enjoyed themselves!
As for my friends, they were all fine! In fact I've got one friend who is totally feminist and into Germaine Greer etc and she came with me to a talk by Yvonne Ridley (the jounalist captured by the Taliban who converted to Islam) and a good time was had by all! I think my friends respect that I've made a choice and I stick to it and now, when we go out and I'm having a weak 'I fancy wine moment' and I do get them, its my friends who help me and say no, you will regret it after etc. I don't wear a headscarf though so I guess that does make it easier for people to accept as I'm not looking drastically different, but I'm hoping the headscarf will be the next step...fingers crossed!
Any more questions, ask away!
