Friends mom thinks my family is weird?

I'm hispanic (Puerto Rican and Dominican) and my friend is Irish or something (idk lol but shes not hispanic). We had a party yesterday with friends and family and I invited her over for a bit. Now, when my family has parties of course theres spanish music and the guys play dominos and stuff. Its loud. Not some social tea party gathering. So when her mom came to pick her up she kinda made a face. I dont want her to not like me or something because her mom is VERY uptight when it comes to certain things. My family is my family and I'm proud of that but at the same time I have a feeling her mom probably went home and was talking about the party. -_- ppl are annoying lol. what do you guys think of this?
