Ignore those students. You can never go home too much, besides its better than p****** away your student loan on 2/3 nights out over the weekend. Personally I go home for football once every 2 weeks and so I will miss like 2-3 weekends this upcoming term when the term is only 6 weeks! Others I know have part time jobs which they have to go back home to do on the weekend. Ultimately you should do your own thing at uni and not buckle to peer pressure as you are at uni to get your degree and yes, whilst you can have fun, it should be your own choice when you decide to and not because your flatmates are giving you hassle.
