Aww that’s nice :)

I personally used the steam card gift idea until I was ready to come out, it would have been odd for me to ask my parents for estradiol on my birthday lol.

If they trust you (I have no reason to think they shouldn’t) they’ll tell you on their own(do let them know you would be ok if they came out as gay/trans it helped me a lot), I don’t think it’s a good idea to assume those kinds of things.

Have a lovely day! 💜
