Can me and my friend easily not get caught while on acid?

So I have recently gotten the opportunity to buy some acid and my friend has been telling me since we did shrooms that if I got an offer to tell him. So I told him about it and am planning to buy it next week. Anyways, so we'd have to do it at my moms house my plan would be to do 1 tab around 8 so it kicks in at 9 ish I know my mom wouldn't come in she's always out by 9. But I don't want us to be loud and wake her up I've never done acid and was just curious can be both be quiet and not be tripping to where we think we are when we're not being loud? Also if we were to take another tab maybe two to three hours in could we act normal about 7-8 hours later? Sorry for the question I'm just new to acid and don't want to "screw up"
