A friend of mine who died about four years ago once answered my question about his continued existence by attributing it more than anything else to "the plentiful company of gorgeous and intelligent women". He had been a lifelong homosexual.
Without claiming to be either gorgeous or intelligent can I just say that I love the company of gay guys because (in general terms)
1. There are no gender politics going on
2. You can flirt with them without any risk of misinterpretation and subsequent bad feelings
3. You can actually talk to them without worrying that they're going to take it as a sign you want to jump into bed
4. You can jump into bed with them without jumping into bed
5. You can discuss relationship problems and sex with them without it being taken as an offer of your availability
6. They go to cool nightclubs and know where to get the best drugs
If you're a straight woman, you choose straight men as lovers or to father your children. You choose gay men for friendship.
That's not to say gay men can't be shallow and bitchy and have a terrible fashion sense like the best of us. And that's also not to say that you can't be good mates with a lover.
apologies for going off topic instromp.
Maybe the woman who heaped up your plate was just being hospitable? In a lot of cultures it's good manners to give the guest the biggest portion.
