so I think I came out to my sister while on vacation

So my mom was away for a couple hours while my sister and I were venturing some another busy consumer district part of the city. I told my sister I'm gay and she told me not to tell mom because she's a bit religious and gullible and stub or or something like that.

So I guess I have my sister's support, but not in a cheery happy way, just more like she don't have a problem since she has gay friends
