New and in trouble!!!

Hey guys I'm new to the stoner world and I'm in a bit of a problem, whenever I would smoke I would stay after school and tell my parents that I would be at an after school program,I know it's kind of a dick move, but anyways it was all going fine and dandy until recently when I found out that we have guests students coming from our home country to stay at our house,5 students to be precise , well now my dads considering quitting his job in order to make sure the guests are in comfortable living conditions ,now don't get me wrong I'm happy for him, the jobs a shit job which pays a few bucks above minimum wage and is located in the middle of nowhere but when he does this that means I won't be able to stay after school and toke up because hell be picking me up from school and ill have to go to the program because hell pick me up, now this isn't the only problem since we have guests coming and we have space limitations it's probable that the guest will stay upstairs and me my sister and my parents will stay in the basement, now this leaves the basement out of the equation so what can I do? My dad will be home every day and ill have to share a limited space with my parents.Now this is just for three months but my dad will be probably stay out of work for a while, so what should I do? If any of you guys have any advice of what I can do to still smoke and not get caught then it would be appreciated by the way we have to have the guests over for money reasons, were kind of struggling right now, and before you label me as an asshole for doing this, I never take money from them and I do everything to keep them happy with me it's just that they're Colombian and they tend to be very anti herb, so any advice is appreciated, Excuse me for my ran by the way lol

Damn three months is a long time. Its gonna be difficult but honestly I think you just have to take advantage of the opportunities when they present themselves. Don't try to force in smoking cuz that will leave you paranoid and much more likely to get caught. Just whenever they are outta the house have a quick toke.

Also I would come up with a system to smoke that makes it quick, safe, and efficient. For example, always having the bowl pre-packed saves so much time. That way if your whole family makes a 5 minute trip to the store or something, you can take advantage and not waste time breaking up bud and packing the bowl. The key is preparation. You have to be prepared to take advantage at any time.
